Hello, the customization of the overflow menu/toolbar doesn't work at my firefox app. The button for "customize toolbar" is gray and not not usable as I used the instructions for the customization. [ https://support.mozilla.org/en-US/kb/customize-firefox-controls-buttons-and-toolbars]

thank you

This happens when I click a link in an email or elsewhere. Firefox responds otherwise, I can open links within Firefox. It used to simply open the link in a new tab.

How can the previous behaviour be restored? so I can open a link in an existing FF window?

I am playing sudoku from https://www.korsordonline.com/cross?id=37707 on Firefox 128.5esr (64bit) on Debian 12. The square in row 3 (from above) column 5 is irresponsive. Clicking on it produces nothing. It doesn't even change colour as other squares do and you cannot write a number in it.

Earlier versions of Firefox never had that problem. Later versions do, e.g. Firefox 130+ on Ubuntu 24 which I run on other hardware.

It seems to be a problem between some new property of Firefox and the developer's sudoku app, since it doesn't occur in other browsers (I tested chrome a while ago).

Could any firefox developer look into this?

Thanks,

Firefox continuously hangs and locks up. It has 15 or 20 processes running and then stops responding when I click on a link. I shut down Firefox and restart and it runs fine. I restarted this session 10 minutes ago and searched for "Limit Firefox sessions" and it already has 14 processes running.

Something is wrong with that.

In "Performance", I Unchecked "Use recommended performance settings" and checked " Use hardware ..."

I have no problems typing in a textbox on most websites, but for some time now, when I type comments on YouTube, the box alternates between working and freezing about every 7 seconds. It will work fine for 7 seconds. Then freeze for 7 seconds, then back to working again.

Any idea what the problem is?

I am a Cacti developer and we are considering switching from FontAwesome Web Fonts to Tabler Web Fonts. However, on Firefox for Windows only, we are having a major slowdown when using the Tabler SVG based webfonts. The page load is first stalled by Firefox apparently loading all the Web Fonts, which would appear normal with any browser (though exceedingly slow on Firefox for some reason).

However, once the page is loaded, when going off tab to another browser tab, and then back to the Firefox tab that includes the Tabler webfonts, there is a 3 second delay before the tab switches. When we enable the performance analyzer, we find that the delay is almost 100% Reflow of the page, even though the page is static as this point (no changes) from the last time it was activated.

We do not have this issue on Firefox for Linux, MS Edge or any other Chromium browser, only Firefox on Windows. I'm using the latest version 134. Should I be opening a bug?

My Firefox desktop app recently updated. After it updated, I now cannot access anything by right clicking. When I right click, a giant window of options shows up (see image). It doesn't change no matter what I click on. When I try to select something in the giant window of options, nothing happens. I'm having a very hard time with it, particularly because I can't open links into new tabs now.

Firefox hangs after starting with "session restore" After I click yes to restore the session firefox just hangs. So I just went right back using Version 138. I reinstalled from scratch still the same problem. At least the older 138 loads my previous session after hanging for 4 hours about and then everything works normally. The newest Firefox does the same, but NEVER resolves, it just keeps on hanging. Doesnt make any sense. What makes the system restore hang this badly. It cannot be old profiles. I completely renmed the old firefox install directory and cleanly installed firefox and it still does this. so it is not inheriting anything. I also allowed it to create a completely new setup in ./mozilla/firefox in the user account.

It also uses more than 117% cpu constantly during this period. See top entry.

Seems like I have to move to Thunderbird/Seamonkey or Brave. Since 2019, Firefox became very "strange"

I used to play World of Tank and look at YouTube on my second screen. Everything went smooth untill this week. YouTube on Firefox on my second screen is lagging or freezing. I tried Opera, I tried Edge it worked fine, but with Firefox, it is no more possible to play YouTube on my second screen while playing. It is not a matter of graphic hardware as this issue only happen with Firefox. I tried to deactivate every module and to reinstall Firefox (either the Beta version) but still got the same lagging and freeze on YouTube. Do you need anything that can help you to investigate this issue, this is really terribly frustrating and boring.

Ever since I got 133.03 my Dell cpu freezes a lot. Over the last hour it froze 15 times. This is terrible reliability.

I hired Dell Tech Support and they checked my software and there were no issues. I have run advance Norton features and there are no problems. Therefore the issue is NOT with my 20 month Dell computer.

Firefox has always been reliable until late August. For four weeks it would freeze and lock up. by the end of Sept it was slightly better and then fine in November. Now it only freezes, put the mouse over the image and it freezes. Play with it for a while and it unlocks.

I am totally fed up with Firefox. I'll be starting my taxes soon and year end things and can't afford to have all these issues and rebooting to help eliminate the issue.

When is Firefox tech support going to help me? When is Firefox going to fix the issue? After Christmas I am looking into the Microsoft software......enough is enought!

I normally use Firefox Developer Edition, version 127 because any later version always freezes my whole computer (probably because I'm using a 15-year old PC). Recently all my extensions became disabled. I'm now also unable to install any extension because it says "Installation aborted because the add-on appears to be corrupt". I found some instructions on Mozilla website about deleting compatibility.ini and extensions folder, but it didn't solve the issue. Now I'm stuck and confused as I suspect some of the extension files that should be in my Profile folder may not be there.

The simplest solution in this case would be to use the "Refresh Firefox" option which resets everything to default settings, but every time I do it my computer freezes until rebooted. Uninstalling and reinstalling manually is also not the way to go, because it retains all the settings.

I've tried installing the standard Firefox browser (v. 119) alongside the Developer Edition but the same issue is there as well.

I'm looking for an alternative way to get a clean Firefox install, so I can fix my extensions.

Additional info: - Your system specs? Windows 10 64-bit, 4 GB RAM, Pentium Dual-core, no GPU - Hardware acceleration? Disabled. - Using any mods? Yes, two. Geckium for Firefox, which always works fine. The recent issue started when I played around with Revert8Plus, but it initially worked without issues.

You have done it again by freezing Firefox in a dormant state after a new version get installed - please STOP this madness!!! How do I 'refreshen' this new version of browser??

Tried to click on Firefox today and browser wouldn't open. So i uninstalled and reinstalled and got the same result. I'm guessing the browser is no longer available for Windows 11 and they're going out of business.

Firefox constantly freezes up as soon as I right click on menus. In the expand/droppdown menu square box that pops up when I right click, is first just white (to text) then goes black and freeze. I understand the Win7 gets no support but does anyone know about this issue and can I go back to a version that does not do that? Preferably a version that does not hound me to update every 10 sec :)

Dear Sirs,

For at least the last two weeks, I have experienced a lot of trouble working with Mozilla Firefox. Just reading my emails is an arduous task.

It crashes, I lose internet connection, it does not "respond," etc., and Symantec Norton 360 cannot find out WHY! I have deleted Firefox and reinstalled it, and it is still unreliable.

Before I have to resort to using another browser, can YOU tell me what is going on. I have a Dell desktop, using Windows 10 Pro (obtained in 2018). Firefox is my default browser. I also have Google Chrome installed.

Please help!

Sincerely yours,
