Firefox: форум сообщества

I’m currently facing a very frustrating issue with Firefox. I have been using Firefox for many years, and it is my favorite and most comfortable web browser for my day-to-day work. I rely on it heavily as all my bookmarks and other important details are saved there.

However, over the past few weeks, Firefox has been crashing more than 10 times a day. I have already tried all the troubleshooting steps available in the forums and through AI support, but none of them have resolved the issue. I also tried installing and using the Firefox Beta version, but the problem still persists.

In our environment, other users and devices are not experiencing this issue, so it does not appear to be related to internal firewall or antivirus restrictions.

Could you please help me troubleshoot this issue? I am attaching the error screen that appears after the crash along with the crash report for you

I am using Firefox on Windows 11, in the process of switching from Chrome.

I run Cockpit (https://cockpit-project.org/) on web servers that I manage, and when I log into it on Firefox the screen flickers constantly, making it unusable.

There is no issue with any other web sites I have visited, and I can still use Cockpit when in Chrome. So ay suggestions on how to troubleshoot and resolve the issue with Cockpit and Firefox?

Hello Support, Every time I open Firefox browser I see this Google Pop-up to sign in. I want this annoying tracker pop up screen to disappear altogether. I see it on the upper right screen it's very annoying and I don't or use or trust Google at all. I've searched through all settings my search engine is DDgo I see no way of eliminating google pop-up. Why I'm I receiving this and how do I get rid of of it ASAP?

Thanks, ---Dave

When I try to log into Tangerine bank I get the error. "We're sorry for the inconvenience. This function is currently unavailable. Please try again later."

This issue started Oct-13-2025 and it appears to work when using Firefox ESR 146.01 but not the regular Firefox 146.01 versions. Tangerine is not giving me information on the error and I was wondering if there is a difference between the ESR and regular version that might clear up this issue?

Warning: Potential Security Risk Ahead

Firefox detected a potential security threat and did not continue to na.nikken.com. If you visit this site, attackers could try to steal information like your passwords, emails, or credit card details.

What can you do about it?

Probably nothing, since it’s likely there’s a problem with the site itself.

The site is ok when I open on another window and even on Google which I don't like.

Attempted to update FF using the 140.2.0esr.msi file. During install it asked for a location of bookmarks (seemed off, like a new install) so the process was stopped. All FF profile files appeared to have been untouched based on their dates. So the following directories: \AppData\Local\Mozilla\Firefox\Profiles\oeg1ubpo.default-esr \AppData\Roaming\Mozilla\Firefox\Profiles\oeg1ubpo.default-esr where both copied to a secondary directory as a safety precaution. Install was restarted and it appears to have again installed a new version with no bookmarks, extensions or password DB carried forward from the previous install, which is not what I wanted.

Can this be corrected, by moving the copied profile back in.

Thanks, Brian

Normally Ctrl+Shift+T reopens the last tab I closed in that specific window, but after the most recent update it reopens the last tab I closed in /any/ window. Is this happening to anyone else?

Until the most recent update, when I opened a new tab a box with the message "Search the web" appeared, and I could enter a query to search. This was exactly what I wanted. Now, the box still appears, but as soon as I type a character the input jumps to the small box at the top left where I would expect to enter a URL. I don't like this, because (a) the jump is disconcerting when I'm trying to type, (b) I want what I type in the URL box to be always taken as a URL, not as a search query, (c) the box in the middle of the new tab is just a waste of space: something held out then snatched away. The solution I have found suggested is to set the resource browser.newtabpage.activity-stream.improvesearch.handoffToAwesomebar to false, but this causes an error message to appear in the search box. I'm sure there must be a way to have the old behaviour back - any help gratefully received.

I'm elderly,so bear with me. Firefox very often slips off the screen or simply vanishes.Often it disappears to a thin,gray line at the bottom. Can't open a document and have Firefox available,too. I'm 84....are my fingers worn out? Dave P.

I am using 140 ESR version on linux with Cloudflare's DNS over HTTPS and with DOH active for some reason resolving a domain like d3oklwo3y1bx83.cloudfront.net will resolve to local host IP 127.0.0.1.

I am using firefox about:networking#dnslookuptool to test resolution of the domain d3oklwo3y1bx83.cloudfront.net Both with DOH on and off the resolution remains local host. I tried another browser on the same workstation and I was able to receive a resolution of 13.225.193.203 13.225.193.133 13.225.193.64 13.225.193.58 Why is firefox ESR not able to resolve that domain? What are causes ?

Is is firefox dnslookuptool results.
