Hello,

Today I updated to Firefox 143.0.3. When done (most of?) my add-ons were gone, in particular all my add blockers, facebook container, etc. Also, my search engine defaulted to Google (yikes!)from Duck Duck etc. I am very specific about trying to block all ads, trackers, etc and avoiding all Google products. Other things stayed the same like cookies preferences.

Is this done by design? Is there a file somewhere that still has all my add-on info, that I can restore.

I really would give up on browsing if I am forced to see ads all the time.

Thank you! Petrus Martens

Hi! I'm on a relatively new to me (refurb) desktop computer running Win 10 Pro (64 bit)* and Firefox 143.0.3.

In the past week both Firefox and Win 10 have updated. I don't know what happened, but now when I boot up or reboot, my computer opens to MS Edge. Yuck!

Every single time I have to reinstall Firefox! Once I do that, all is well again. I have all my bookmarks back, etc.

It also keeps changing my "default to Firefox" browser setting, turning it OFF, while I'm using Firefox. I repeatedly have to keep going in and clicking to make FF to the default browser again.

Why is it doing this? How do I stop it?

Anyway, I know I can't delete Edge or uninstall it. How do I shove it back into the black hole it has lived in until now?

Thanks very much in advance for any help offered. :)

Hi Firefox Team,

I know how hard you guys work and I've used you almost exclusively since the beginning in 2003 and talked a lot of folks into switching to you over the years.

I'm so frustrated about your decisions to change the options for what we users want on our home page and new tabs. Seems I can only use a blank page or your default home page. And if I want my normal home page I need to click on the home icon. In the course of a day, that's a LOT of extra clicking or the alternative, typing my search query into a tiny URL bar.

Are you planning to change this? Or is this Mozilla control by default the new norm? I'm so sad to admit to be exploring Mullvad and Brave now. Never would have even considered it, even though I'm consciously weaning off other US digital products.

Thanks for any suggestions and for all you do. (Yes my IOS is up to date)

Firefox is the default browser and pinned to the taskbar. When clicked, Firefox automatically opens places an additional icon in the taskbar. Once Firefox opens, in the second icon, any new links open in tabs, which is my preference.

The first image is the pinned icon in the taskbar. When hovering it only displays Firefox. The second image is the additional icon, when hovering over this icon the active page thumbnail is displayed.

Prior versions of Firefox did not have this behavior on my Windows 11 desktop PC. I've tried various settings in about:config but cannot resolve this issue. Is there some reason two icons are now required in the taskbar when running Firefox?

Firefox has always been my workhorse for my business, but after the last update, I can no longer open Firefox on more than one desktop on my Mac. Firefox requires me to designate either a specific desktop to open Firefox on--or to open it on all desktops. This doesn't work for me because on each desktop I open a different site on Firefox. I will no longer be using Firefox for work, and since I was using Firefox because of what I perceived were stronger security measures, I am very disappointed. I really wish software engineers would stop "innovating" and fixing things that are not broken.

I opened Firefox on one of my computers as usual today but the whole performance changed. Used to go to my home tab and select various news sites to see what was happening. First, when I scroll down the bookmarks, I would hit the "news" and click on it so all the sub items would stay in the scroll, but instead of that, it wanted to open every item as a new tab. When I finally started opening the various news outlets, it opened them in new tabs, it had always opened in the same tab. Then, I couldn't close the various tabs it had opened. I would go to the tab and hit the "X" but it didn't close the tab. I had to use a drop down menu to close a tab. And when in a site, I used the scroll button on the mouse, instead of scrolling, it made the page larger or smaller instead of going up or down. What could make such a change in behavior? I opened up the 'settings' on it and looked at 'tabs' and they were the same as the ones that are on this computer that works as expected. Both computers have it set to open all previous windows and tabs. Both have the same settings for 'tabs' and 'browsing'. I don't get it. Both are version 143.0.3 (64-bit) I have Ubuntu OS.

Hello..

Trying to make the Firefox as my default but... the Web browser" is not visible in Settings.

PLEASE guide me to the right link..

At this time the Microsoft Edge is selected permanently.

Any suggestion is welcome.

When trying to sign-in to online banking, an essential button cannot be clicked on, because it is flashing. (see attached image - the blue bar at the top is flashing so I cannot make the dropdown security selection.) This does not happen on other computers or on Safari browser, so it must be my Firefox. Any ideas how to fix this? Any suggestions would be appreciated. Thank you so much - Chrissie.

I usually have a lot of pages open on Firefox and the display in the dock gets packed, if you will. I would like to see an option in the settings to turn the dock display off, just for your program, Firefox. It would be nice to toggle this option. I've searched for about an hour trying for an option and a solution. Thanks for your good works. I'm on an early Mac Mini 15.7.1

Take care. Have fun. //... Joe [edited email from public community support forum]

This issue just started recently, say within the past 2 weeks Mid September forward.

Only happens in Firefox, Chrome not having an issue. Open Facebook tab and it opens fine then after 10-30 seconds, it crashes with this error "This page isn't available right nowThis may be because of a technical error that we're working to get fixed. Try reloading this page."

Have disabled all extensions, cleared cache multiple times with no success.

Appreciate any other suggestions on fixing as I'm not a big fan of Edge. Old school. lol

Thanks - Dan

When I turned on my computer this morning, and opened Firefox, it froze, and had to be process-ended by Windows.

Subsequently, it also caused Windows Explorer crash.

I was forced to hard-reboot my computer, and restarted it to find all my tabs gone and unrecoverable, and all cookies deleted.

However, my browsing history remains.

Furthermore, my attempt at recovery of this data via the automated backup taken Monday 29 September 2025 - three days before this post - accomplished nothing.

I have looked in several places here, and found no help at all in recovering lost tabs. All threads remain unresolved.

Please provide troubleshooting assistance ASAP.

(And please be aware that the software had to be opened in order to post this question.)

I was able to stream news from CTV news site but for some unknown reason I cannot stream it like I used too I cannot figure out why! Something must be wrong with my setup. Please help me fix my problem.
