Using desktop 141.0, noticed issue of the hand pointer either not appearing, or appearing for less than a second and disappearing when hovering over buttons/urls/etc elements. Sometimes it stops being buggy for a minute or so and then goes back. I can't figure out the exact cause for this, but maybe going outside of the window of the browser ? Consistent in the safe mode, on different websites. See the gif for the visual

Hi, I want to make a simple extension for Firefox that auto toggles vertical tab based on the aspect ratio of the Firefox window. I found `sidebar.verticalTabs` in about:config that toggles vertical tabs, but a simple googling tells me that it is not possible for web extension to modify about:config values. Is there any other API that toggle vertical tabs? Thanks!

Hi I recently installed a new webpage in Wordpress. It worked and I got the theme window on my website. I use two browser - Chrome and Fire fox. Now time for me to start installing a new "ready made" theme. It all looked good on Chrome when finished. I opened the same link in Firefox, but Firefox has not changed to the latest theme. https://condorentalpattaya.com I am totally out of clue. Removing cookies and other memory related functions does not work. I do not use Cloudflare. It works on my mobile.

??? Thanks in advance, have a nice day

Firefox 141.0 update has made everything move very slow. Pages will only partially load then take several seconds to completely fill out. If you click on something, the little dot on the browser tab will be gray for several seconds and then eventually turn blue and open the page. It's like it's having to think a little bit before opening the page. Everything just seems delayed.

Since I can't comment on this: https://bugzilla.mozilla.org/show_bug.cgi?id=1976656

> This will allow websites to ensure that all of their scripts are protected with integrity data.

Anyone knows how would this help content blockers (uBO...)? We won't be able to block, redirect or modify ads and tracker scripts (including inline scripts) any more if the websites implement this?

Emergency!!! I just arrived home from a trip, and on my primary pc, I had saved say 50 tabs over a number of years. I was/am interested in syncing, but I had taken no known actionable steps to do so - but when I arrived home, my primary pc did not open the previous session. I lost everything. Spent hours trying to recover the previous session. Then, I simply decided to go back seven days and restore those tabs. Eight Hundred(!!!!!) tabs were restored, from what appears to be from each of my computers. I am now deleting the 750 unnecessary & repetitive tabs (again, on my primary computer), I am now *scared to death* to boot any of my other computers and have all of my history wiped again. WTF!!!??? Thank you very much!!!

Firefox has started redirecting to advertising pages after clicking on a link. Only on 1 site. The site loads but not quite correctly. Normally has information about movie ratings show up when you hover over pictures. Have to double click (double load) to get where you want. Does not do it with Edge. Used to work fine, just started.

I find that the Firefox Browser continually goes back pages when Alt-Tab between Firefox and other applications, especially applications like Xero and even online banking.

For example, on Xero, I bring up a Profit and Loss then go the the bank transaction list with selections. Then Alt-Tab to another application like an Adobe document. Then Alt-Tab back to Firefox and it has gone right back to the Profit & Loss.

This happens continually and drives me nuts! Is there a fix for this please?

I'm using a laptop with Windows 11.

Websites are grainy after Firefox Update Late July 2025, is there a fix for this?

Since I downloaded the new Firefox update yesterday, the lettering on all websites is grainy. I used Chrome and not getting the same grainy-look to the lettering and logo's. To be honest, it is worse on my monitor, but can see the graininess on my laptop as well.

Is there a fix to this, or do you suggest something I could do to fix this on my end? Would deleting Firefox and reinstalling fix my issue? I would rather use Firefox over any other browser, because more added security is provided for your users, and less selling of information.

I tried to screenshot the graininess to add to the images, but it subsided upon capturing.

Thank you, Michelle Rodrigues

Hello, I'm not sure which genius decided it would be a good idea to have the latest update (141.0) automatically change the Firefox settings to 'clear history when Firefox closes' but that is what happened on both my computers... I obviously didn't notice just lost years of research history as well as all my tab groups. No information in session history at all (before today). Nothing at all in session restore. Is there ANYTHING that can be done to restore my history? Genuine suggestions appreciated.

I can see all my bookmarks, passwords, history etc. on mobile but this Sync feature refuses to import the bookmarks to my desktop browser. What is causing this? I have Synced then Unsynced dozens of times with the bookmark option on and off, signed in and out several times, reinstalled Firefox several times. There has to be a way that I can just get my bookmarks onto my desktop. It cannot be this complicated.

Hello, since I installed the Firefox 141.0 update today, I can't login to Reddit. I tried logging into Reddit right after updating Firefox, so did a System Restore to see if that corrected the problem, and it did.

To double check, I installed the Firefox 141.0 update again, and encountered the same problem logging into Reddit again, so it's definitely this new update causing the problem.

I've attached the Reddit messages I get. The 1st is the initial message, and the 2nd after I retry logging in.

I would greatly appreciate help with this.

Thank you,

I am running Firefox on a Windows 10 desktop. Recently (within the last couple of months) whenever I close Firefox I get logged out of my account. I don't recall this happening before. It doesn't happen when I close Firefox on my MacBook using iOS.

I can't find any option or control that tells Firefox to logout of my account when the browser closes. I have automatic updates for Firefox enabled so I should be running the most up-to-date version.

Is there some control that I missed that tells Firefox to logout of my account when it closes?

When trying to sign in to Lastpass. I get a notice to "Set your permissions to strictly necessary " but there doesn't seem to be a way to save that choice and it always reverts to "Voluntary data collection" thereby making it impossible to use Lastpass. I can use the extension on other browsers and even on Firefox Nightly. Any help would be appreciated.
