Firefox Support Forum

I have been using an old version of Firefox (109.0.1). I am not typically using a newer version because of an essential - to me - add-on which hasn't been updated, and which doesn't work in more recent versions.

On macOS Sierra this old version of Firefox crashes. Troubleshooting mode (I was prompted a number of times) and restarting the browser appears to eventually resolve the crash, but finally there is an issue with the memory and the browser doesn't "work."

The reason for the crash given is " MozCrashReason: Failed to load critical module "resource://gre/modules/WebNavigation.jsm" "

The crash report text is reproduced below: __________________________________________________________________________________________________________________

I've been using firefox for last 15 years now to do my online banking with RBC. As of 2 weeks ago it has failed to open online banking on the RBC website. Google chrome however works. When speaking to RBC customer support they say it is a problem with firefox and will likely go away once firefox updates to a newer version.

Hope you can help with this issue since my browser of choice is firefox. Thanks

I am on a unstable internet connection and while trying to download a large file it gets often interrupted. By default Firefox deletes the .part file and I am forced to again download from zero. Is there a config that I could change so Firefox keeps .part files so I could continue resuming the interrupted download?

Your browser suggested that we use Thor Browser which looks like a scam.

I CAN NOT DELETE THE FILE OR FOLDER AS :I DO NOT HAVE PERMISSION TO DO THIS.

I WANT THIS REMOVED SO DON'T IGNORE THIS AND RESPOND AS TO HOW TO FIX AT [removed email from public support forum]

I have Firefox set up to basically clear itself of all history, cookies, data, etc. each time it closes. As a result this means I need to log into my password manager each time I open a new Firefox session, rather than every 72 hours which is the setting I have put in the password manager itself. I know how to make exceptions for websites, but it's making an exception for an extension that is confusing me. Any help is appreciated!

I want to attach a file and I click on a button (everything works perfectly on Chrome). When I click, in the console I get this error:

(firefox:3264): Gtk-WARNING **: 13:52:46.781: Can't open portal file chooser: GDBus.Error:org.freedesktop.DBus.Error.UnknownMethod: L’interface « org.freedesktop.portal.FileChooser » n’existe pas pour l’objet à l’emplacement /org/freedesktop/portal/desktop

Of course, nothing happens when I click. I have Ubuntu 22.04 and apparently Firefox in installed with snap, and I have this problem since snap is used to install Firefox.

If it's useful:

This message is the last I'm writing before I definitely move to Chrome. I hope I'll get the help I couldn't find on other places (I saw a lot of answers telling to deactivate snap, adding a ppa or some solutions like these).

I just upgraded to windows 10 and have been restoring my computer to functional status. I have found that discord, tiktok and several other sites will not play videos on firefox. I have tried troubleshooting mode and private so i know it is across the board. I have also tried using addons to fix the problem to no avail.

When I try to access my Etrade account the connection fails. Sometimes I can reach the log in page but cannot log on, Usually, I can't even access ETrade. I can log on using Microsoft Edge but not with Mozzilla,

I go to youtube, open a video and the audio plays just fine, except there is no visual. The video says its playing and I can hear it normally but I can't see anything. Subtitles show up, but the place where the video is supposed to be is just blank, the same as the background of the page. Weirdly if I click the settings button on youtube, the one next to the sign in or account button, the video will display as long as that menu is up. If I close the menu the video goes away.

I have refreshed firefox, deleted and reinstalled firefox, removed all my extensions, turned hardware acceleration off (and then back on when it didn't work) as was recommended in a similar post a few years ago, and restarted my computer. Youtube still won't show me a video. It works fine on chrome, just not firefox.

I uploaded a screenshot of an ad, which doesn't play but shows the outline of the video player, a screenshot of a normal video where the area the video should be in is just more indistinct background, a screenshot of the video appearing normally when I have the settings menu open, and a screenshot of the captions loading properly over an empty void.

Edit: I installed the Enhancer for Youtube extension? Which I haven't ever installed beofre? And now Youtube works? Why

2nd Edit: Its broken again. I changed literally nothing, just restarted my computer for an update but im getting blank screens again

Hello - Firefox to Safari bookmark syncing used to work seemlessly between pc and ipad. Noticed it's no longer working. I've done all the resetting/restarting/logging out/uninstalling/reinstalling recommended. It still won't sync. I ended up installing Firefox on the iPad to get the bookmarks from PC. That sync works (takes a while sometimes). But it will not ever update the IOS from the last time it worked (maybe 3 months ago). I can erase IOS bookmarks and reload from iCloud, but the files are months old.

Has this function just been removed?

I have lost my personal bookmarks list on the Mozilla Firefox Home Page. I now have numerous bookmarks, some which were in my personal list and some that I may have used in the past, but deleted them. Others are from an unknown source. Maybe a Firefox generated list. They aren't all familiar. Can Someone help me find my personal list that existed before the last update and restore that list.

After updating to FF 114, I noticed that my history and cookies were no longer being cleared according to my settings. Also, a particular page is now being opened as a pinned tab.

I reverted to FF 113, hoping that this would be fixed in 115. Today I tried 115.0.3, and history is still not being cleared. I have again reverted to FF 113.

I am on Windows 10. My history settings are to use Custom settings and clear history when Firefox closes. Cookie settings are to delete cookies and site data when FF closes.

Is there any intention to fix, or is this some new behavior that I am stuck with? Also, is there a way to clear the pinned tab behavior?

Thanks.
