Open a Telnet with Firefox link and bad things can happen

I happened to come across a site with a number of links, and I chose the one who happened to be a telnet link. This is my experience, and I had to put myself in the shoes of the average user who knows nothing about programming.

The link that has caused problems of Firefox where Firefox was chosen to run it is:
Telnet://DXC.nc7j.com:7300

Click on the link and Firefox tells you you have to select a program to open the Internet shortcut Shell extension DLL. I've never heard of this, and I have no idea what to do here.

Choose to open with Firefox.

Now, if an error handling routine had taken that Firefox, which is not able to Telnet, was chosen by the unconscious person behind the keyboard to move forward and do Telnet, the error handler advises the user on the fact that this Protocol is not taken in charge and kill the process that is going to run out of control if not. Or to open the program which will run the Telnet session.

Better yet, I clicked on the link Telnet and offer a better description of the choices.

After all what happened, that I have installed a browser based on Chromium, iron and he opened a Telnet session window immediately.

This did happen, clicked on Firefox to do this chore and was welcomed by an opening endless empty tabs and the browser is closed, he raised and I was off to the races again. And once again.

OK, so this isn't getting us anywhere.

Firefox opens once more, this time hitting the big red X to close it and leave asked it to close but many tabs invites when even sitting there.

I chose to run CCleaner and I put that to blow the Firefox Cache and session. Run CCleaner and tell him to force Firefox closed when he asks that Firefox is open.

If by chance, Firefox launches once again, the timing was perfect as the file that was the origin of Firefox open wasn't cleaned yet, then run the CCleaner a few times. When Firefox is the opening is no longer, we are in the world of mental health.

Now, I could go to reset the Tools Options Applications tab and search for Telnet and replace the use of Firefox with 'ask me '.

Fortunately, I know a little bit more than some about the computer, and I knew I had to use a utility to clear the Firefox cache.

You have a description of the problem in your knowledge base, but he has Firefox open the empty tabs without end, but Firefox was closed and the situation is under control... Restart Firefox manually, start a new session, and then enter the menu Tools and difficulty setting.

There is an article in the knowledge base on this theme, but there the user to close Firefox, and then everything is back to normal. You can open Firefox and enter the menu to resolve the problem. There was a mention in there any malware as a possible cause of the constant reopening that I lived, but Malwarebytes scans were clean.

"Well, this is awkward!" I have seen that nice touch to Firefox for many years and may I want to congratulate those who thought of that one.

There are a couple of settings related to resume your previous session after a crash:

(A) resume automatically, but if Firefox crashes twice in a row, displays a list of windows and tabs and let me choose. (default)

(B) does not resume automatically, always show the list of windows and tabs and let me choose; (I recommend this approach) or

(C) never automatically resume and do not display the list.

Switching to B or C requires a visit to Firefox about: config preferences editor.

(1) in a new tab, type or paste Subject: config in the address bar and press ENTER. Click on the button promising to be careful.

(2) in the search above the list box, type or paste sess and make a pause so that the list is filtered

For "B":

Double-click the browser.sessionstore.max_resumed_crashes preference from 1 to 0 (that's a zero).

For "C":

Double-click on browser.sessionstore.resume_from_crash preference to change its value from true to false.

    The question may be because of your corrupt cookie (cookies.sqlite) file

    Rename (or delete) cookies.sqlite (cookies.sqlite.old) and delete the other files of cookie present as cookies.sqlite - journal in the Firefox profile folder where the cookies.sqlite file has been corrupted.

    You can also check whether DOM Storage is enabled.

    Create a new profile as a test to see if your profile is the source of the problems.

  • Cannot open the PDF with Firefox 11.0

    Firefox automatically upgrades the version I use. Since he has recently been updated I can't open pdf files. Am facing a blank page. I went through some of the suggestions on these pages, and when I opened the tool window, there is a caveat:

    Firefox PDF Plugin for Mac OS X is not compatible with Firefox 11!

    Is there a way around it? Or it's time to say goodbye to Firefox and go on Safari?

    I had the same problem. Go in Tools > Modules > Plug-Insand disable the plugin Adobe Acrobat. Once I did, my PDFs opened in preview.

  • I have problems with the links and footer

    I have problems with hypertext links (they sparkle and also highlight other text on the page) and also the footer space for always lights in site preview mode, even though I did little master and home page and the following pages.  This happened only after I loaded a file of MUSE in the current version of Muse CC put running up-to-date on the imported file to Muse.  Please help me Adobe Community.

    Once you have opened the file 2014.3 muse you will not be able to open it in a previous version anyway. In order to keep the updated version.

    In this version, Yes, Muse will run an optimization when you open a site. My suggestion is that optimization is made to save the file, so it doesn't have to do it again. I am convinced that a full download should solve your problem. I had a few sites that I need to do a full download myself and all is well.

  • PDF. JS is no longer compatible with Firefox 35 and more. Why is it not be deleted?

    Noticed that PDF Viewer PDF. JS is not compatible with Firefox version 35 and more.
    Then why not delete it?
    Wine

    Since you have already installed, why not just update?

    For what is 'user' vs 'Developer', like the other reviewer mentioned, pdf.js is already integrated into Firefox for quite some time now and is enabled by default. There is nothing that needs to be installed unless you want to keep testing the 'extension' version which updates with new features and fixes more frequently than update of 6 calendar weeks for versions of Firefox. If this is the case, just update.

    https://github.com/Mozilla/PDF.js
    Scroll to the getting started > browser Extensions, Firefox-> development Version = click on it - then 'Allow' the hanging door that appears below the address bar on the left side.

    I saw your answer 2nd straight - on PDF. JS modules Web site. I don't see that what listed there more. I have no idea if or why it was deleted, but it will always update this area for users who have already installed. If someone else wants the extension, I guess they will have to get it from GitHub. I can only speculate that, overall, it is sufficiently developed by now that Mozilla doesn't have users more to test the advanced version and code that comes in Firefox works well enough.

  • Beginner jQuery is having trouble with the links and the page redirect and page caching.

    Hi all

    I'm trying to update an old legacy of multipage site (each page has headers html etc.), adding jQuery Mobile. Most of the time it goes well, but I'm having some problems with the links, the redirect of the page, and caching.

    I write javascript like this...

    < script >

    -do things - then-

    Window.Location.Replace ("Page1.html");

    < /script >

    and links like this


    < a class = "-ui ui-btn-b btn tsize1" href = "page2.html" rel = "external" > page 2 < /a > "


    CACHING ISSUES


    On many pages - such as those that I have problems with, I've added no caching of code as...

    < head >

    < META HTTP-EQUIV = "Pragma" CONTENT = "no-cache" >

    < META HTTP-EQUIV = "Expires" CONTENT = "-1" >

    ... more...

    < head >

    Problem: for example, I can go to Page 1 and click on a link to go to page 2 and page 2 has the lines "no cache" header. The problem is that a fresh change of page 2 does not appear even with no cache lines above and even if I hit refresh in the browser that I thought it was supposed to reload the page (live get of the site). On the contrary, it seems to continue to see the old content before the update.

    In another case I could be on page 21 and click on a link that goes to the publicationfootnote22 and made a few treatment database and then goes to the page33. In this case, my fees top22 updates are not appearing and showing just the old cache data.

    Q: what is the best way, at least while I am writing code, to force the Page to refresh (non-cache), I can see my updates all the time, because otherwise it becomes very confusing because I'm sure you know.

    Thanks in advance: Dave

    Hi Dave,.

    Are you handy with your developer tools? It's always where I head when I need to look inside something. Before getting anywhere in addition or developed, check the response code you get for the page request and see what is the numeric code. If it is 200, you get a new copy. If it is 304 then your browser is striking the same content or something in your UI is to preserve the previously loaded document fragment.

    Photos make it easy, Chrome this is grabbing a small page for the first time and with disable cache enabled, and we get the status code 200:

    If I keep refreshing with "Disable cache" activated so I keep getting GET/200, copy fees.

    However, delete the "disable cache" to speed things up and the server and the client negotiate and check if she even needs to send you the document (if she thinks she's changed), and if not, of course you GET/304, or "load cache:

    Whenever I update I get GET/304, hitting the cache.

    Make sure your requests are GET/200 if you expect not to be cached.
