When testing our web application, I can consistently get the tab to crash in Firefox (not other browsers). This happens even when running in Troubleshoot mode.

A few of the submitted crashes: bp-f1e47e32-aa7e-4080-880c-34f160250710 bp-622b9363-fa50-4b15-b605-87c3e0250702

Can anyone tell what is causing it to crash, and if we can do something to fix it?

Hello! I've been seeing some strange behavior on firefox launch or on new profile launch. There is a popup during startup, can't see it on the screen but I can see it in tray. Is this normal or no? I observed it on two different hp notebooks so far.

I have created several groups (currently 4 with a total of 11 tabs combined). When a group is closed, do those tabs become inactive, reducing their impact on Firefox/computer performance, or do they still remain active and impacting overall performance?

Hi,

Whenever I try to watch videos on Anime Slayer APK in Firefox, I get a message saying the browser is “unsupported” or the video just won’t play. I’m using the latest version of Firefox on Windows, and I’ve already cleared my cache and disabled extensions, but the issue persists.

Interestingly, the same videos work fine in Chrome and Edge — so it seems like a Firefox-specific problem.

Is there some setting or add-on I need to enable to make it work? Or is this a known compatibility issue with certain websites?

Thanks for any help you can provide — I’d rather not switch browsers if I can avoid it.

After exporting bookmarks.html from Ffox on old computer, importing it to Ffox on the new one, all good, except that bookmarks toolbar shows on the imported list but doesn't display as toolbar.

How can I sync my groups between different instances of Firefox (other computer)? That should cover both active and saved groups to have real usefulness. Thank you

From a week ago, for no apparent reason, I get "403 Forbidden" when I try to read articles on seattletimes.com using my prescription to the site. It's a total block of the site.

After rebooting, the site is OK until I log in, as needed to read particular articles. Then nothing is accessible any more.

The trouble is the same on all my laptop/desktop computors, which all have Firefox and are in sync with it, and once I log into the site on one of them it's blocked on all. But this doesn't affect my android phone, on which every article can still be read.

This is clearlly therefore a Firefox problem.  I'm worried that I'll have to switch out of Firefox to some other browser.  This is unreliable behavior.

Previously, recent websites, and pinned websites would show on the Firefox Home / New Tab page. Now, it is completely blank, except for three rows of blank boxes, which are unresponsive, a search entry, which works, and a weather app with menu.

I've searched and searched for a solution, find limited cases previously, but no solutions.

Hi. I changed my default to Firefox but when I open a tab that darn Yahoo keeps coming up. I restarted my computer and everything. How can I get Firefox to be my search engine?

I usually use Nightly as my default browser in a Windows 11 system. Recently I started to get a new error message showing up when I try to select multiple messages in Yahoo e-mail. I select them by clicking on the first message, then holding down Shift and clicking on the last message in the range. That should turn on the selection boxes for all the messages between the two.

Now, when I press the Shift key, I get an error box right on top of where my mouse cursor is, so it interferes with me. The top of the box says "mail.yahoo.com", which is the web-site I'm signed in on. Then it has a link with the text "Login - Sign in to Yahoo". Below that is an ad for all the wonderful things I can get by signing in to Yahoo. At the bottom is an error message, "We can't generate key points for this webpage."

I tried the same action in the current General Release of Firefox, v140, and this does not happen. I suspect that this is an intrusion by some sort of AI software, but I don't know what setting might have been activated to turn this on. Does anyone have any idea how to turn it off?

Lately when composing an e-mail at gmail.com on my Firefox the attachment button is missing. As well all styling aids are missing (font, fontsize, bold... etc.). This problem does not arise, when using Chrome or Windows Edge instead Firefox. But I sure want to stay with Firefox.

Firefox version 140.4.0 Windows 11

Thank you

Any time I allow a website to use my location on my home computer, it places me in a suburb in Las Vegas. However, I live near Seattle. This happens on multiple websites including Google Maps and Uber Eats, and on other browsers my location is correct. I'm not running any VPNs or proxy servers, I've verified that my IP address is linked to my correct location, and I've deleted all cache and cookies ("Everything" for time frame) from my history. Is there a way I can have an accurate location again?

I am trying to recover my bookmarks/passwords/settings after a recent crash but when I sign into my mozilla account where I had everything synced, I get the default bookmarks. I have tried all of the backup options in the forums and searched my pc in AppData and my profiles are no longer there.

Is there a way to restore my synced data from a few days ago?
