Firefox Support Forum

For the past week, when I login any streaming services (Netflix, Hulu, etc) I get a message "Gah, your tab just crashed". After going through every add-on and plugins I found that 'Widevine Content Decryption Module provided by Google Inc' causes this. Disabling widevine allows the tabs to load but then I get a request to enable DRM to play the videos and if I do it just enables widevide again and the tab crashes. I never had this issue before. Is there a different plugin I can use or a way around the DRM request? Widevine version is the latest is updated.

I have this problem CONSTANTLY with 100.0. i keep 2 browsers open, (1 Email, 1 ebay) After 5-10 minutes, firefox "Loses" internet connection. and i have to clear the startup cache, to get back online, only for it to happen again... and again, and again, and again! Didnt have this issue with the previous update. PLEASE HELP! and please keep the answers simple, im not well versed in programming language

Many file types are no longer listed under Settings > Applications>Content Type at about:preferences#general. I used to be able to click on a file in an email like a Word or Excel document, and it would come up on my screen. Now Firefox asks me to Save them. I don't want to automatically save files without first looking at them. How can I get those file types in the Application list again?

I have attached a pic of the file types I have left to chose from. There used to be a lot more. How can I get back all the missing choices I have had there for years?

I'm running v100.0.1 (64-bit) on Win10. I've seen others report this problem but haven't found a fix listed anywhere. <Ctrl-P> or Menu->Print results in the same problem. The print overlay starts up (say Print in top right corner), spinning wheel above Preparing Preview in the center of the overlay... Never ends. I have to Esc to get out of it. Happens on any page. Print dialogue works fine on same pages with Chrome and Edge.

Hello team,

I'm not sure what happened, but I was not able to open Firefox after restarting my PC. I currently run Windows 11 on a fully upgraded rig.

Up until today, I have been trouble free. Error 1: "Firefox is already running, but is not responding. The old Firefox process must be closed to open a new window."

I tried several options - and have been googling/trying several steps for a couple of hours (after each step, I restarted the PC):

1. Uninstalled and then Reinstalled a fresh copy of Mozilla 2. Attempted to use Command Lines to open Firefox https://wiki.mozilla.org/Firefox/CommandLineOptions 3. Opened Profile Manager and attempted to create a new profile - when I did this the new profile would not display in the Profile Manager, but it would display in the Profiles folder under Appdata [I tried this multiple times] 4. Deleted the profiles.ini file

After deleting the .ini file Error 2: "Your Firefox profile cannot be loaded. It may be missing or inaccessible." 1. Uninstalled and then Reinstalled a fresh copy of Mozilla 2. Opened Profile Manager and attempted to create a new profile. After following the Profile Wizard, another error pops up: "An unexpected error has prevented your changes from being saved."

I am completely stumped. I hope you can help, Sean

Hello, I recently migrated to a new MAC and now when I download a file and click on "show all downloads", it opens the about:downloads tab and not the downloads list from the library. Is there any way to force Firefox to open the Library when I click on see all download please? Thanks

I can't no longer use "wetransfer.com" Their homepage does not load properly and no matter what I click on this page it starts using the CPU 100% and slows down everything and nothing happens anymore. I whitelisted this website in all privacy-extensions, and because in a flits I saw that "firefox essentials" was blocking something - despite the whitelist - I uninstalled it. To no avail. Firefox 100.0.1 (64 bits) under Windows 11 home 64 bits. How can I find out what is the problem ? Thanks for helping out.

Greetings. I can't open most sites I usually visit (even google.com) via my Firefox 98.0a1. This happens since today. All error codes are SEC_ERROR_LIBRARY_FAILURE.

Tried to:

• Disable DNS-over-HTTPS.
• Disable HTTP/3.
• Disable proxy (never had it enabled anyway).
• Disable sending info to Firefox developers.
• Change settings of DNS-over-HTTPS.
• Restart the browser (after each action).

Nothing helps me... But I still can visit some websites, but most common resources are not working for me. Please help me because I can't use Microsoft Edge without getting mentally ill. :/

Starting last night Firefox will not let me download anything. If I click on a download link, my Mac toolbar goes gray like normal, but no download dialog box ever appears. I have confirmed the dialog box isn't hiding behind any open windows on my desktop, and I have tried rebooting my system with no change.

Please help me fix this.

I have two PDFs that I designed and uploaded to our website, but the headline in both displays with clipped characters in Firefox. Different fonts were used in both and the issue is the same. I even tried adding more tracking then re-uploading, the issue persists.

I checked in other browsers and the text displays as intended. The attached screenshots show the issue in Firefox, compared to how it should look (viewed in Chrome).

It's only this one line of text that is affected and I don't know why.

I have Firefox 100.0.1 on my Mac desktop, and Firefox 100.0 on my MacBook Pro laptop. I can no longer access my Microsoft OneDrive account via the web on my desktop, but I still can do so on my laptop. I have gone through your posted troubleshooting steps for Firefox on my desktop, to no avail. How do I get my desktop back to version 100.0 so it will work again? I can access my OneDrive account via the web on my desktop when I use the Safari browser, so the issue is definitely with Firefox version 100.0.1, and not with my desktop.

$ dnf list installed | grep firefox firefox.x86_64 100.0-4.fc36

Since upgrading to Fedora 36, Firefox seems to have stopped being stable at all. Having any add-ons enabled causes webpages to frequently break. Even in troubleshooting mode, I get a tab crash immediately on start, and infrequently during later browsing.

Troubleshooting mode has the same issues, trying a completely clean profile has the same issues. Chromium works with no issues.

See tab crash report here: https://pastebin.com/wNPFhpgN

Hello,

I just upgraded to Firefox 98.0.1. And there doesn't seem to be an option to add Pocket suggestions to the homepage, as there used to be.

You can add Pocket articles that you've saved, but not suggestions from Pocket.

It used to be under settings - home - recommended by Pocket.

Has this been removed from the options?

Thanks, Taylor

My picture-in-picture remains in full screen, even if I double click with my mouse. When I click the ESC button it just closes completely. I have restarted both Firefox and my computer, but I keep getting the same problem. Not just in YouTube either, also on other websites.
