The Firefox prefs.js file was quarantined by avast yesterday. Message indicated malware had infected the file. Now when I click on the Firefox icon the MSN browser comes up. How can I get back to using Firefox safely? Can I uninstall Firefox, then re-install it to make the problem go away?

Hi,

My partner has an issue with Google working within Firefox (FF). The problem started around 27 April 2022.

In short:

• • Both gMail and Google Drive keep saying “Ooops … the system encountered a problem (#2003) - Retrying in x s…” and “Not Connected”.
  • The above message may stop for a period and then gMail within FF fails to render its pages properly. Icons go missing. For example the check boxes to the left of the emails disappear while the remainder of the subject lines remains. Menu icons across the top of an open gMail document disappear (like Download, Report Spam and Delete icons ….). This seems to suggest a cache issue.
  • Search within FF using Google fails also. After entering search terms and pressing ENTER, nothing happens.

Note:

• The stand-alone Google Chrome environment works fine. So gMail, Google Docs, Sheets etc work OK in the stand-alone Google Chrome app.
• Duck Duck Go search works within the FF browser.
• I have noted that if I simply log into MY Google Account under Firefox on her PC the same problem occurs.
• If we log into my PC the problem is not apparent using either of our Google Accounts. So it appears to be an issue on her PC.

I have tried :

• Flushing the cache in FF for all time, including data. Then rebooted.
• We have followed your procedures under “Help” ie Runs a Firefox a tune up; used “Diagnose issues” and “cleared the startup cache”.
• Have run Sophos AND MalwareBytes across the whole laptop. No PUPs or malware detected.

I uninstalled FF using Revo Uninstaller which initially uses the standard FF uninstall exe then it scans the drive for removes all FF files and entries within the Registry; then I re-installed the latest version of FF. Rebooted. No luck here either. I assume there is some remnant file that remains on the hard disk as some settings are retained after a new install.

Hardware: Lenovo ThinkPad , model 20QFS00B00. OS: Windows 10 Pro, vers 10.0.19044 Build 19044, 64 bit Firefox browser: is up-to-date; vers 99.0.1 (64 bit)

I can't find any recent issues related to this specific problem. Please advise what to try next.

Of course I'm happy to provide additional info if required or work through different scenarios to isolate the issue(s).

Thanks in advance for any assistance, Steve Gee

I've had a problem recently with some sites (such as support.apple.com, but also others) loading very slowly or not loading at all.

• Restarting Firefox fixes it for a short while
• I've tried changing to No Proxy from Use System Proxy Settings - this, like restarting, helped for a short while
• Unchecking DNS over HTTPS: DID resolve the problem but I'm curious as to why. I enable it with Safari with no problem.

I have Spectrum they gave me a new modom which gives us a speed 200mbs or more. Google gives us over 200mbs but Firefox give us 146mbs. Can you give us more speed. Thank you for your help. Ronald A. Tappan

I have this box that shows up over the top of any video application on my firefox browser since my most recent update. It doesn't appear on other browsers. How can I remove it?

Firefox only shows a black box when i try to run an embedded video. It works fine on other browsers, specifically Microsoft Edge. I ran it in troubleshooting mode which fixed the problem temporarily but reoccurs when computer is off and then turned on.

bold textFrefox crashes all the time. It will only stay on for a minute or less. Here at the crash reports:

Hi, when I visit some websites, the pages do not work properly. The page does not want to upload properly and links on the page do not work. Can't log in to a page I have the latest version installed.

I use two displays, suddenly it is no more possible to move the Firefox- and/or Thunderbird-Windows from Monitor to the other monitor, grabbing its mainbar and trying to move, the window sticks on half way and then flops back.

I got mad at a website that wouldn't let me right click menu to save pictures, so I stubbornly saved them via less efficient means, in the process I picked up the Long Screenshot extension and this had an error shortly before or after I had an issue with Lightshot not appearing, other extensions did not appear either when I added them during this time period, but now these all appear with the exception of Lightshot, which gets deleted and reinstalled only to not appear, that of course being the problem, though I will also say that a right click menu not being there is like reaching onto my computer and pulling my finger away, sites that do that should be given the cold shoulder somehow, at least.

The warning "This file contains a virus or malware" keeps appearing from my downloads progress bar even though the files have been deleted and the download history has been repeatedly cleared. I've restarted my mac several times to no avail. Please can you help? Magnus

When navigating within retailer web sites, some clicks, such as searching for their nearest branch, consistently produce an Access Denied message, such as the following one:

Access Denied You don't have permission to access "http://www.argos.co.uk/stores/?" on this server.

Reference #18.d639dd58.1652362340.afeb7586

I get a similar response when trying to open some web sites, such as Sainsburys.co.uk which has just responded with the following 403 message:

403 ERROR The request could not be satisfied. Request blocked. We can't connect to the server for this app or website at this time. There might be too much traffic or a configuration error. Try again later, or contact the app or website owner. If you provide content to customers through CloudFront, you can find steps to troubleshoot and help prevent this error by reviewing the CloudFront documentation.

Are such searches controlled via Firefox? If so, do I need to change a Firefox setting to overcome the problem?

My problem is this:

If I click on the open new tab button, and then I keep my cursor there, such that I get the little tooltip "Open a new tab (Ctrl+T)..." , Firefox will stop the address bar from updating---it won't show my keyboard inputs, not will it search, or do anything else. This will resolve itself after I move my cursor away from the open new tab button and the tooltip stops showing, even my inputs will appear there.

This quite annoying, especially when opening a tab to search for something quickly...

My microphone does not work properly in Firefox, it sounds very low and bad.

I have a Corsair HS35 Stereo headset and my sound driver is Realtek HD Audio 2nd output.

I have tested my microphone in other browsers and other kind of applications like Google Chrome, Brave, Windows Voice Recorder, WhatsApp Desktop, etc. and the microphone works fine. It only works badly in Firefox.

I did the test with a portable version of Firefox, and, as with the installed version, the microphone was malfunctioning.

I've also noticed that Firefox lowers the microphone volume automatically (how do I prevent this?), yet even if I turn it all the way up it still sounds very low and bad.

What can I do about it?

Thanks for the answers

When I open a website, the message "Firefox is already running" comes up every time. Task manager says nothing is currently running. I have to click "close Firefox every time I go to a website. Can you help? Thanks Alan Murray

After experiencing some problems (saved tabs being empty, menus gone etc.) I read about restarting into troubleshoot mode ("Help"-"Troubleshoot mode" menu) which solved those problems (I believe "Troubleshoot mode" might be the same as "Refreshing" Firefox, from what I've read -correct me if I'm wrong) . I'm on Firefox 98.0.2 on a Mac.

Following that I quit Firefox and opened it again the normal way which I assume means it went into the normal mode as before, but I realized all my extensions were gone! Reading through some older postings I see they're in a profile named "legacy_BAK.profile", and in addition I have recent Time Machine backups, so any files aren't lost, but I guess the simplest way to fix this is to re-install my extensions -but most extensions (inside the "extensions" folder within the profile folder) only have a cryptic numbered name with and .XPI extension. So how can I find out which extensions I used to have, and better yet -is there a quick way to just install everything back again with a single click (installing it from the legacy profile folder, or just moving something over to the new folder etc.)?
