How to install multiple versions of Firefox
For many years, I use Firefox on multiple versions of Mac OS X.
For compatibility reasons, I have to keep the last 3.6.28 and I would like to use the latest version.
Until version 35.0.1 it wasn't a problem at all to have multiple versions installed.
The problem began with 36.x and remains also with the latest 38.0.
Problem: all booksmarks disappear when switching between versions. The browser history also disappears.
How to reproduce the problem:
I throw the old version 3.x, all booksmarks are there. Then I stop 3.x.
Then I run the latest version 36.x or 37.x or 38.x and all booksmarks are still there. Then, I'm closing this version.
Back to 3.x all bookmarks disappeared. In any version of FF.
I need to recover the Firefox folder in the application to return to the 35.0.1.
Any help would be really appreciated.
Best wishes from the Germany,
Boris
If you use the time Machine, then you could try to restore files from the backup.

Hung Nguyen
Hung Nguyen,
The installation of drivers for all targets in real-time remotely is more or less the same. First install the driver (in your case the NO-Sync) on your PC, then install it on your system remotely through MAX. For step-by-step instructions, see install the software on your NI CompactRIO controller.
See you soon,.

Oracle Version of policy template - how deploy us multiple versions?
Oracle Version of policy template - how deploy us multiple versions of the same rule of thumb in determining server? The intention is to have the rule of thumb in parallel of the versions available and the client to the web service to decide which version to use?
You don't have to reboot - just put "cache.loaded.rulebases = false" in the application.properties file (its value is 'true' by default). If you rename this * after * deployment then it could give inconsistent results, but must ultimately resolve itself.

Photoshop 4 and 7 upgrade, now Windows 10 does not accept PS 4. How to install my versions?
Hi Tuulah6441378,
Photoshop 4 and 7 are very old versions, downloads for them are no longer available and the operating system you are using is the most recent, so there will be compatibility problems.
Adobe has not tested these applications on newer operating systems.
Please see, historical version of Adobe Photoshop - Wikipedia, the free encyclopedia

How can I install two versions of firefox that run independently of each other?
I want to use an installation of firefox as a normal browser who remembers all the tabs I opened and a facility other than for viewing html files. I would like this second installation do not open all tabs from my previous session, do not load all plugins and the history of my main installation of firefox, but as the html file I want to open.
Thank you
File associations are subject to operation of Windows and its "limits.
IMO, you need to have the profile that you want associated with the default profile HTML files. I'd do it by editing the profiles.ini file to change the default profile that is labeled as default = 1, , but someone else might have a method 'smooth'.
But then all you want to open in the default browser opens in Firefox with this 'profile HTML '. When you use Firefox as default browser in Windows, it will only use the profile marked in the profiles.ini file by default when the default browser is called to open.
If it seems absurd, don't blame me - I beat my head against the wall for nearly 10 years on this default browser / 'thing' default profile, every time I screw up a profile when the default browser opens the wrong profile, after, I was ' dicking with "several profiles. Of course, I brought that on myself by having too many versions of Firefox are installed and having too many profiles.If it were me, I would use the 2nd, lightened profile and get used to using file > open file... and drilling through the file system of the Explorer to find the file I want to open and open the open a file dialog box.

Can I install newer versions of Firefox OS on Alcatel OneTouch fire? How?
I'm trying to follow a suggestion (https://support.mozilla.org/en-US/questions/1087727#answer-791503) I'm on another question I ask here, but I feel that's not possible, so I would ask here too specifically.
I have an Alcatel OneTouch fire (first version), and it updates only until Firefox OS 1.3. I would like to upgrade to newer if possible versions. The list of official devices (https://www.mozilla.org/en-US/firefox/os/devices/) says nothing about the Firefox OS versions run these devices. Isn't it weird?
Can I build a newer version of the operating system and the flash on my camera? It is latest updates because Alcatel / my carrier do not have available or is there a technical limitation that prevents me to run newer versions of Firefox OS on this unit?
Thank you!
Hi, some versions of compiled community seem to be available to the https://vegnuxmod.wordpress.com/hamachi-alcatel-otf/

Install older versions of firefox for compatibility testing (4 &; 6)
I need to install older FF versions to make compatibility test of a web application.
When I look at the index of the versions available at http://releases.mozilla.org/pub/mozilla.org/firefox/releases/ I don't see anything for version 4 of firefox. What gives? Where can I find the files to install this version. Ditto for version 6
With the new model of quick release, each new major release is considered a direct update to the previous, without support for the older versions. As a result, Firefox 4, 5 and 6, are supported no more, while 7 is up-to-date and 3.6 is still supported. When the new plan scope of release of support is implemented, there will be that a new version major support of the regular releases with minor updates in 3.6 How is now along the side. This is why Firefox 4, 5 and 6 are not on releases.mozilla.org, although there is a folder for 5.0.1 without the binary inside for some strange reason. The field of releases.mozilla.org has mirrors for managing the high load needed for the current download versions. Everything else is on . mozilla.org and http://ftp.mozilla.org/ note asking people to link to the other server when possible for reasons of bandwidth.
As to why you could not access the FTP server, it is accessible by FTP instead of HTTP, so you have something blocking. Just a guess so.

It's very frustrating because I had not requested an upgrade (this has caused me problems in the past)
so, while I wait for a solution to the question of selenium, how can I roll back to an earlier version of Firefox (that works with Selenium IDE)
Here are 23 https://ftp.mozilla.org/pub/mozilla.org/firefox/releases/23.0.1/win32/en-US/Firefox%20Setup%2023.0.1.exe [en]
