Firefox Community Forum

Hello,

I can no longer log into twitch, it says my browser isn't supported.

Before you say anything: I have the latest version of Firefox, I have disabled all addons, cleared all cache and cookies, even tried a complete, clean re-install. I can log-in in other browsers, just not in Firefox. I have disabled enhanced tracking protection as well, didn't work.

Does anyone have an idea?

Firefox has been running smoothly for the last 6 months. Recently I started receiving Firefox Crash Reporter dialog boxes when opening the app. The app never opens, but I receive three crash reporter dialog boxes.

What I have tried: Repair Reinstall Deleted every Mozilla folder in App cache and other device locations. Did another reinstall. App never loads and I receive a crash report. Updated Windows. Restarted laptop. Etc. Everything else on the device runs perfectly.

I've been having a problem with FF for the last two weeks. At times downloads accessing web sites are slow or even get hung up. Usually reloading or refreshing the page fixes the problem. I tried a FF safe boot and things seemed to work better. I have had the same four extensions for quite awhile. Are there any reports of UBO causing issues?

Hi all,

I installed firefox with all suggested options, when I open google play books and click on a book it keeps loading but nothing happens. Works in chrome and edge.

Thanks

Hi, We are using Horizon VDI terminal server. Firefox is installed on these servers. Some users get Firefox is already running but is not responding error. Ending Firefox via task manager does not work. I log off the user and have them log in again, but it does not work.

When I check, I see that the user's profile file cannot be created on any terminal server.

Is there a solution to this problem?

Last night, firefox just disabled all my addons and all attempts to reinstall any failed with a red warning that everysingle one I had or new to add failed. I tried a few suggestions I found online like refreshing, clearing cash, restarting, but nothing worked.

I have a vwersion 88 (and some change) running on a windows 7 computer.

Any wisdom is highly appreciated.

If I won't be able to fix this, I'll just move on to a different browser after using it everywhere for so many years and it will be sad

When I am working with several open applications I sometimes need to slide the browser window over to I can see both open apps at once. Now when i pull the browser window partially off screen to the right it bounces back at full size. This is frustrating and time consuming to resize again. is there a setting to turn this feature off?

When using website at https://tools.myfooddata.com/nutrition-facts/170112/100g/1 , the search box titled "Search for A Food" shows up in Google Chrome, but not in Firefox. In Google Chrome, it can be seen in the upper left part of the web page, but I can't find it in Firefox. Also, when I click on the button called "Instructions" on the web page, nothing happens in Firefox, but when I click on that button in Chrome, it opens up an instructions menu. What can I do about these things?

Fire Fox - This profile was last used with a newer version of this App - Create a new profile.

After logging into my account, I saw a Fire Fox page showing new features. Upon downloading Fire Fox, I saw the the above message. I didn't want a new profile, but there wasn't an option to close the window and to just continue to use the newer version that was already installed ???

I tried Control / ALT / Delete . Upon restarting it showed the same message! I uninstalled Fire Fox, which surely has not helped things.

Am I able to restore the profile from the "newer version"? Otherwise, I will probably have to setup Fire Fox from scratch and have lost all bookmarks.

Thanks so much for your assistance. Myles

I am blocked from opening my Asus Router in Firefox for Mac. I added the router's address to every exception list I could find in Settings and still no luck. I can reach the router through Safari and through Firefox and Edge on a Windows 11 machine. I like my present Security settings on my Mac except for this annoyance. Can anyone suggest a workaround or a setting change that would fix this issue? Thanks in advance for your help.

ver: 134.0.1 Windows 10 Pro I have Firefox set to open filetype PDF in Browser. Normally I use IDM which automatically download PDFs, unless I press ALT key while clicking DOWNLOAD button, then it does not, in order to allow Firefox to handle the PDF.

Firefox presently does nothing. With filetype setting set to Open in Browser, Firefox Does nothing. If settings are set to Ask, it does not ask. The PDF filename appears at bottom of screen momentarily.

ver: 115.19.0esr Windows 7 Utl 7601 The exact same behaviour was also seen on a Windows 7 system running Firefox 115.19.0esr. PDF is also set there to "Open in Firefox". Again, when ALT pressed when clicking Download button, Firefox does nothing.

Installed Firefox on my laptop. Already running on my desktop.

Whenever I try to open a link, I get: Get an app to open this 'microsoft-edge' link

Your PC doesn't have an app that can open this link. Try looking for a compatible app in the Microsoft Store.

Is this Microsofts way of saying "Use Edge?" Can I change settings to make it work?

I am a heavy Firefox user, and have been using it (and its predecessor) since Netscape. In the last year, the size of my Firefox profile has more than doubled, from 500MB to 1.3GB. What's the probable cause(s), and what can I do about it?

Every time I try to get on Discourd I get a message that says An error occurred during a connection to discord.com. PR_END_OF_FILE_ERROR

Error code: PR_END_OF_FILE_ERROR

I'm attempting to set up sync between my windows laptop and my new android phone. The phone has firefox loaded, allows me to pull up the 'sync and save your data' page, allows me to choose 'ready to scan' and presumably successfully scans the QR code displayed on the laptop (the laptop prompts me to approve the new device). Then the laptop indicates I need to wait to approve it on my phone, and the whole process stalls. The phone continues to display the mostly blank white screen with only the "moz://a" at the top and the spinning blue circle in the center. Eventually the whole thing seems to time out and I receive an error message on the laptop saying "websocket unexpectedly closed" and "device pairing failed".

My two hypotheses are that either still having my old phone (which is being retired to at-home use only, and I'd rather not de-sync) still synced is somehow interfering (seems unlikely), or that something about the new phone's software is interfering in the sync (seems unlikely and way out of my league in terms of troubleshooting around).

Help please?

I can't use Google search, Java not running yet it was the other day, I have 'Open264' plug-in, in 'about-config' Javascript.enabled is set to 'true'- I tried toggle it and re-booted but still same.

Then, I tried in browser 'safe-mode', lo and behold that solved the problem.... why is this? What I didn't mention is before doing all this I tried Java script and that work OK.... but not Google search.

Thanks, Dave
