Firefox Community Forum

I am using an extension to monitor websites. I would like to start it as homepage. Unfortuantely, it does not come up active. It requires a manual reload (Ctrl-R) because it doesn't fully start.

Is it possible to automate this initial reload?

If not, can the extension developer force the reload on browser startup?

Thanks

A major bug unfortunately means that Firefox cannot open in full screen anymore. I have tried restarting it more than a dozen times, but it still doesn't work. Please solve this as soon as possible; I am begging you, I’m on my knees for the developers.

With the progressive rollout of tab groups having ended (I am assuming that because they are available by default in fresh installations), I would expect them to be available when I sync with my Firefox profile. However, when I sign in to the browser to sync all my settings, the option disappears. I am more interested in why the rollout never reached me than being told to enable tab groups in `about:options`. The profile switcher is also not showing up, but I am not sure if that is still in beta.

In the last few days, after some minutes of usage, parts of Firefox become unclickable:

- I can still click on tabs to change tabs. - When hovering over the cross button to close a tab, it changes appearance as it should. Clicking the button does nothing. Ctrl+w still closes the button. - Clicking on the address bar does nothing. - Cannot click on back, forward, refresh buttons. - Cannot click on any add-ons. - Cannot click on preferences. - Can click on the button to open a new tab. There, I can enter an address. Once the page has loaded, address bar becomes unclickable again. - Bookmarks toolbar is still working as expected. - Keyboard shortcuts (ctrl+t, ctrl-w, ctrl-l) still work as expected.

I'm running ``` Mozilla Firefox 138.0 20250428130755 20250428130755 ```

on Manjaro 25.0.1 with GNOME 48

This is the link. I can't send animated images as the text is too small, so I'll describe it instead. It's so hard as a loyal fan, I'm crying.https://www.bilibili.com/bold text。There is a bug. Why does the Bilibili website not display the corresponding screen when I try to move to it? Speed playback cannot be used at all, and there’s also the issue of not being able to use fullscreen on Firefox. Are you forcing me to use another browser?

The A4 print preview (and the printout itself) from the PDF file is shrunken. I've tried printing from Edge and everything works normally there, so it's a Firefox problem. How do I fix it?

Hi there,

I'm using the AI chat sidebar in Firefox desktop, and I've noticed that some AI chat providers offer voice and screen sharing features. However, instead of asking for microphone permissions like it usually does in a regular tab, Firefox seems to ignore the request entirely. Is there a way to get Firefox to display the permission request or to automatically allow it in this case?

Thank you!

I'm currently using MacOS 15.4.1 Sequoia with FireFox 138.0.1. It works fine after updating from 138.0.0 on my primary (Administrator) account. However, there is a second User account on this MacBook Pro laptop, used by other family members. All is not well here... Firefox updated itself from 137.0.0 recently and now will not run on the User account. On startup, it asks for an Administrator password to install a Helper tool and then will proceed no further. I have tried :-

Making the User account into Administrator - still hangs Cancel and re-start FireFox - hangs! Re-start the MacBook from cold - hangs! Cleaned Firefox installation and folders in the User Library (both User and Administrator) - still hangs! I'm aware there are two Library folders, one each for the System and one for each user, didn't touch the System Library. Added a new User account - it works! So maybe something in the System Library is the culprit? I've always regarded that area as "off limits" to us mere mortals, so please, not the "Wipe it and Start Again" option.

I don't really want to kill the User account, there is a lot of data in there and surely will miss something important if I delete it.

Summary, 137.0.0 worked, it updated to 138.0.1, it hangs up! I am unable to fix it. Any offers guys?

Today, when I logged onto my computer, something went wrong and Windows had to repair my C: drive before it could continue to boot up. Once it did, Firefox was changed. Some of the shortcuts on the windows were missing and I couldn't get them back with the command to "Dismiss" the substitutes. More serious was my new inability to log onto any sites besides Mozilla's. I have tried restarting the computer and turning off my router and turning it back on again. All the while, my Android phone account is able to login to some of these sites without difficulty. I need to diagnose this problem and fix it. How can I do that, please?

Hi Forum! My Firefox is constantly (weekly) asking to update, even though we're on the latest version (right now we're on 138.0.1 (64-bit) I've reinstalled Firefox a couple times but the issue still persists. I'm not sure what my next steps would be.

Thank you all in advance, I appreciate your knowledge and time!

When I open any stream, it takes about 2.5 seconds from the start of the page loading to the appearance of the stream image and playback. For comparison, in version 137 it took about 1.0 seconds.

I tried to launch the browser (Firefox 138.0.1) in troubleshooting mode, and also created a new profile, but the problem remained.

I also downloaded portable versions: 137.0.1 - everything is fine. 138.0 and 140.0a1 - slow loading.

I also have Zen Browser installed (the latest version is based on 138.0.1) - everything is fine.

Copy, Cut and Paste are not working in Google Sheets or Google Docs using Ctrl-X, Ctrl-C or Ctrl-V. Other control combos do work such as Ctrl-Z, Y and F. These features are working on Chrome with the same files. I disabled extensions and tried the Troubleshoot mode. Neither helped. Using Firefox desktop 138.0.1 on Win-10 Pro.
