"Bookmarks and history system is not functional" with corrupt files found by Avast and slow loading Web sites ONLY in Firefox

Firefox is the only browser that allows me to connect with my microphone. I need to use this feature for an online class. Earlier tonight, the message invites me to grant or deny permission to site class to use the microphone stopped appearing and without this registration only will pick up all the sounds and I can't save anything.

I tried to quit and restart Firefox. I had a few extensions in use at the time, in particular Session Manager. The allow/deny message would not always appear, then I restarted my computer.

Now when I open Firefox, I see the message error "the bookmarks and history system won't be not functional. In addition, the browser loads websites extremely slowly; It takes several minutes to load each page or for me to be able to click on anything whatsoever (bar URL, menus, etc.) my other browsers (Internet Explorer and Chrome) are functioning normally and loading Web sites at a normal speed. I tried to download the latest version of Firefox, but it does not solve anything. I also tried to restart the computer again, but that didn't help either.

I ran my Avast software system check, and it has mounted as the following files under "C:\Users\ (me) \AppData\Roaming\Mozilla\Firefox\Profiles\Irozixj7.default ' are 'damaged and unreadable ':
-cookies.sqlite - shm
-cookies.sqlite - wal
-localstore.rdf
-places.sqlite - shm

There was one more problem on the analysis, but it is probably not relevant: the file "C:\ProgramData\Microsoft\Windows Defender\Definition Updates\{9A2C6FA7-E04E-4819-B86A-8363A9D1E42A}\mpengine.dll" it says "the system does not have the specified path. When I tried to follow the path shown, one of the files (I can't remember who) said something along the lines of "you can't access this folder, you want to allow access to this file permanently? I said yes and was able to access the folder.

I tried to add the extension in Maintenance of places, but the speed is too slow to download anything. Trying to access any results of the menus in the Explorer freezing for several minutes then thaw but with the menu still unopened. As a result, none of the solutions found here (https://support.mozilla.org/en-US/kb/fix-bookmarks-and-history-will-not-be-functional?esab=a & as = aaq) seem to work.

My questions are the following:
-Is it possible to understand what caused the problem in the first place?
Is there a way for me to fix it without losing my bookmarks and history?
-How can I prevent that from happening again in the future?

First of all, I recommend you backup your Firefox settings in case something goes wrong. See back up and restore the information contained in the profiles of Firefox. You can copy the folder of your Firefox profile together somewhere outside the Mozilla folder. To quickly access this folder:

Help > troubleshooting information > "view file" button.

Then, to keep this file open, exit Firefox and try to move "damaged and unreadable" files to another folder. With the exception of localstore.rdf, which stores the positions of windows, toolbar tools and other data non-essential customizations, other files appear to be specific session files that we hope, are not critical. If you restart Firefox, should he behave more normally?

If this is not the case, try to create a fresh Firefox profile. It will be the Flash plugin, which is the control of sites use usually to connects to your camera or microphone and other plugins, but otherwise will be a new configuration. This article has the commissioning steps in the Profile Manager: use the Profile Manager to create and delete profiles Firefox.

If the sites are functioning normally in the new profile, you can import your bookmarks from your old profile, as well as the copy on the other files that do not appear to be the cause of the problem. Some trial and error may be needed to determine that. This article has a few tips: recovery of data from an old profile.

If the new profile is not better, you can exit Firefox and use the Profile Manager to return to your original profile.

Any improvement?

  • How can I fix this error? The bookmarks and history system will not functional because one of the files of Firefox is used by another application.

    I tried many solutions being posted in the support forum. I went and deleted my places.sqlite file so that it has created a new profile. I tried to restore my favorites, and nothing happened.
    I went and found out that I had a places.sqlite.corrupt file. As suggested by one of links provided in other articles, I removed the other places.sqlite files and then renamed just corrupt as places.sqlite. I restarted firefox and still nothing.

    One possible cause is security software (firewall, antivirus) that prevents or limits Firefox or plugin-container process without informing you, possibly after the detection of changes (update) for the Firefox program.

    Delete all rules for Firefox and the plugin-container in the permissions list in the firewall and leave your firewall again ask permission to get full unlimited access to the internet for Firefox and the plugin-container and the update process.

  • Problem with pdf for the opening of the health gov Web site.

    Problem with pdf for the opening of the health gov Web site. I use my ipad in Safari and have installed the application to adobreader. Healthcare gov support only suggested to disable the pop-up blocker. I did, and I couldn't always open the file. No problem on a desktop computer regardless of the browser.

    In my view, they spend on their web server to a document ECM server authentication. Someone else has the problem?

    I tried the Penguin, Chrome and Atomic browsers on the ipad and the same issue.

    Okay, actually, I think that there is a problem with the type of form. It is a form of a special kind (called a form XFA or Designer, for what it's worth), which can be opened with Adobe Reader and only on Mac or Windows. There is no iPad software that can read these.

  • Acer Aspire laptop with Vista Home Basic Edition does not, System Restore does not, sfc, find corrupt files but do not repair. Need help!

    Hi, I have an Acer laptop Aspire with Vista Home Basic Edition that came pre-installed, so no records only the disk hard drive partition.

    I turned on my laptop today and it starts but the loading bar of stalls at the black screen with "(c) Microsoft Corporation" and dragging green. The slide bar will continue to drag, but nothing else happens which means that I understand even as much as the login screen. I rebooted and tried Windows recovery, but the only remedy to what he suggests is a restoration of the system, which does not have any point, I try to restore it.

    To remedy this, I have connected in safe mode and ran the SFC command prompt. It scans my system and told to find corrupted files, but he can't heal some. This is where my knowledge limit runs out. I don't know how to fix the files that the SFC cannot. (Also I created a journal using the findstr command prompt and checked but it say anywhere that it was unable to fix it so I'm not even sure how to identify corrupted files)

    As it's an Acer laptop, Aspire I'll try their eRecovery tool to return my computer to factory settings, but it won't work in safe mode, and as I said I can not connect normally. I tried alt and F10 at the initial boot screen when I turn on, it loads the windows files and shows the Acer "Please wait a moment" screen and then nothing happens again.

    I can't afford to get it fixed, and there is no chance I can get a new laptop. Any ideas/help? Thank you.

    I use an old dell works well with XP, is there a way to get around this, I already have photo professional, eos utility etc. of my rebel...

    ANY help would be greatly appreciated

    Having been forced to upgrade too because I need to process RAW images from the 2 7 using Photoshop, I can tell my updates went well. I bought Win 8.1 & done a clean install on a new hard drive & waited to win 10 out & from my old programs would continue to operate. 10 once was readily available that I made an another clean install on another hard drive as an installation & nine 64-bit (added 16 gigabytes of memory also) & things was great when working in Photoshop, BUT for all those who 7 2 treatment check CR2 what device profile is best. By default, it chooses an Adobe profile that works very well with my other camera files but Standard camera looks better with 7 2 files.

    (My computer has provisions for 5 internal hard drives & I 5) I can easily re boot for XP or Win 8.1 if I need to use one of my old programs, but so far, I've been running Win 10 on my office & XP on my laptop.

  • The event log does not start error 31: a device attached to the system is not functioning

    I can't get the service to start on my winxp sp3 pc event log. I have tried everything I know:

    • Running sfc/scannow
    • Reset permissions
    • Search for malware and viruses
    • Rebuild the WMI
    • Create a new account
    Nothing seems to work, I think that this is related to an error in hardware/device, but I see no problem in Device Manager. Can someone point me in the right direction to get this resolved? I don't really want to have to format or restore my PC...
    Thank you.

    * EDIT * well it seems to have fixed myself, I used regedit and navigate to the key:

    HKEY_LOCAL_MACHINE\System\CurrentControlSet\Services\EventLog

    There, I found some records, I deleted the folder "Powershell" and the "Internet Explorer" folder, and the event log service, and then began. I had uninstalled IE and Powershell but these records were still there so I thought I would like to remove to see if he has made all the difference.
    Thanks for your time!
