Firefox Community Forum

bold textI don't know enough about settings/conflicts to resolve this. I had no problems for years, but this has been an issue for the past six months. AT&T has tried to help, but it just won't work. I have had this email address for almost 40 years, and I really don't want to give it up.

After the latest version was updated, Version 149.00.7, on my laptop, on 27 March 2026, the browser closed midway while I was working, and now I can no longer access Firefox.

When I click on the Icon to access I keep getting the following error message as per the attachment:

I have uninstalled Firefox and re-installed it THREE TIMES already', but I still get the same error as before, as per the screen print provided.

I have even tried to install Firefox with custom settings, but then in order to proceed with the installation the ONLY button to proceed was the "UPGRADE" option.

I am at my wits end because this is totally unacceptable and the updated version obviously DOES NOT WORK!!!

Your urgent attention and prompt action in sorting this out will be appreciated, thanks.

When I bring up the certificate-expired URL

<https://oaklandwiki.org/>

in Firefox 149.0 on Windows 11 I am told "You have added a security exception for this site." But not how to remove it. How do I do that? I did not see anything in Settings or about:config; did I miss it?

I wanted to use the new VPN feature and the icon initially showed up in the top right, but it has disappeared and is not present in "customise toolbar" or privacy settings either.

Youtube is pretty much unusable for me after the newest update. It loads fine the first time after I open or restart Firefox but after than it slow down to a crawl and it takes minutes for anything to load when I click on videos and menu buttons. It's not my internet since the website works fine in other browsers and it also works fine in private mode in Firefox for some reason. I tried clearing caches, permissions and anything related to youtube in my Firefox profile folder. I also tried creating a new profile and it does the same thing. The only way for it to work normally is using private mode.

Hi, I use a website called Slickdeals which has a lot of thumbnail photos showing the product on the homepage.

Firefox seems to have a problem with it where Chrome does not.

Scrolling fast throws it off...the screen turns white and I have to wait for the images to load. Also, the scrolling tends to get choppy while using my touchpad scroll.

I've tried disabling hardware acceleration, disabling smooth scrolling, and clearing cache/history.

Sometimes the cursor lags about a second from the arrow to the hand pointer on links to click.

I have fast FIOS internet and a laptop with 16 GB RAM.

Thanks!

How do I get the star I can click to show list of bookmarks? Just installed Firefox on new laptop and friendly star is missing. Had same problem years ago but Firefox popped up with the answer before I had to ask

I previously accidentally removed notification permissions from discord. I'm trying to reanable them, but even when i enable the settings in discord firefox will not give me the popup to turn on notifications. when i click on the usual permissions tab myself it simply does not show the notifications option. they are not blocked in my firefox settings, and other sites like youtube and twitter work perfectly fine

Firefox is causing my wifi adapter to shut down

Running firefox for any length of time will shut down my wifi adapter at a random moment. The only solution is reboot

Using opera, the problem does not occur, I can run opera continuously without problem. Running firefox at anytime will cause the fail at some point.

Im running windows 11 I have run firefox in safe mode Disabled all addons Set to “No Proxy” Disabled power saving on the adapter Replaced firefox with the ESR version 140.8 , previous version was the latest I note that there are up to 11 firefox process instances in task manager (all cleared when firefox is shut down) Firefox is set to update automatically Several updates have occured during this problem Disabled hardware acceleration Cleared cache Latest wifi driver And a few more that I cant recollect at the moment

Running out of hair to pull out

Any idea’s?

When using DuckDuckGo Search I cannot drag and drop the search URL into my Bookmarks. I can drag and drop a Google Chrome search URL into my Bookmarks as usual. Also, the correct URL is not shown for the search using DuckDuckGo. See attached screenshot.

Please resolve.

Simple problem; complex solution? I work between two laptops and send files from one PC to the other by email. This week I could not download the sent files on Yahoo Mail. It literally just stopped downloading. I checked my security settings, created an exception for Yahoo Mail, double checked MS Defender, but nothing seems to be blocking it that I can see. I tried to review other sources, but could not find something for this situation. Help?

After today's update, March 25, 2026. I cannot print correctly. When printing from a page with drop down menu's, Firefox is printing every option on the menu. I have tried Refreshing Firefox, Clearing Saved Print Settings and rebooting. Anyone know how to fix this?

I found there're several folders at my "%APPDATA%\Mozilla\Firefox\Profiles", but only one of them works on Firefox. I also checked "about:profiles", but there's only one that is running. And I can't find where to load other profiles.

What happened is that - my PC crashed, after reboot, I found Firefox became a new one. I went to "%APPDATA%\Mozilla\Firefox\Profiles", and luckily found old data still exist safely. But I went to "about:profiles", there's only a new profile. And I don't know how to load the old profile.

So I tried copying files from other profile folder, and paste to replace (or overwrite) the profile that is working. IT WORKS. The new profile is replaced by the old. But it's not a regular way to do so. How to load a profile fold?

I read the article about having 50 GB of free VPN use after I updated Firefox today to version 149.0; however, I don't see anywhere where I can enable the VPN. I've checked in the "Customize Toolbar" section, and I still couldn't find anything. I don't understand, the article made it sound like I should have access, but I've also read that it's not out for everyone yet?
