I use a note keeping app that saves copied snippets from the web with the source URL. I've noticed that Firefox has recently started stripping URLs - the SourceURL field now only contains the domain in the html format payload.

For instance if I copy a snippet from a wikipedia page in Firefox and view the HTML format information stored on the clipboard, I see:

Version:0.9 StartHTML:00000133 EndHTML:00000344 StartFragment:00000167 EndFragment:00000308 SourceURL:https://en.wikipedia.org

Previously, the source url field would contain the full URL for the page, and if I try in Edge, it still copies the full URL for instance:

Version:0.9 StartHTML:0000000150 EndHTML:0000001067 StartFragment:0000000186 EndFragment:0000001031 SourceURL:https://en.wikipedia.org/wiki/Cat

The text/x-moz-url-priv field also only contains the domain now instead of the full URL. Is there a setting or something to restore the previous behavior of storing the whole source URL to clipboard?

Firefox just automatically updated and now when playing video while not being the selected window (eg watching a video in the background while doing something else) it plays at a noticeably lower frame rate.

I was using my computer today and everything was working fine, when I closed and reopened Firefox it automatically updated, I have changed no settings anywhere on my computer or in Firefox but when i alt-tabbed to a different window while watching a movie after the update Firefox started playing at a low frame rate.

Any idea what could be happening? it seems to be caused by this latest update.

(I have seen posts from some time ago that seemed to be having a similar problem but the solutions from them do not seem to work).

Dear M, the toolbar themes are worse than glass, in readability

How do I change the color of bar and tabs, so I can spot the active tab without ruining my eyes and mood? (The only themes in 157 that are not from a child's dream are still useless, because the tabs have nearly the same color as the bar, and, as you pointed out, lack the previous visual accents like shadow or line.) I understand there is a very good reason to remove the old themes, but please explain how to change these two tings:

- tab bar and tabs brightness - bar colors or brightness (lower bar with address/search field and bookmarks bar)

Or better still, put back the theme I chose that gives me a dark mode fitting in with Mac apps. (Since I don't know if there is a backup, I cannot even figure out the values of old themes.)

Thank you

Gesturefy, Version: 3.2.19 keeps loosing my gestures in FF 157.0 (64-bit)

It constantly defaults to the initial state

This has only happened since the latest update to Firefox

Is there a way to back up either the Gesturefy, app or the profile which hopefully includes Gesturefy, settings?

Many thanks for help

Hi, my spell check only rarely works, I have tried adding more dictionaries, but as it works sometimes, I assume it is something else that is the problem, I had asked about this in another thread, but cannot find it.

So basically if I right click there is no spell check option most of the time. I have also installed LT check spelling and Grammer, not if that interferes with spell check, I feel I had this installed after the problem started, I tried disabling it, but spell check still only activates intermittently.

First the laggy, extremely slow issue was just noticed on YouTube. Now I notice it on Rumble and other sites. For now, I have to abandon Firefox and use an alternative browser. I've stayed with you for years. Maybe it's time to part ways. I really like your browser. But, it has become nearly non-functional for me.

I've set my local open-webui as the browser.ml.chat.provider as https://llm.local/ and upon right click to a page and saying "summarize this" the side bar is opening. But the prompt doesnt get pasted to the webui.

Doing that while the sidebar is already opened works fine!

Any suggestions how to fix this?

When Fidefox updated to 157, it kept all my settings, but it will not allow my windows default PDF viewer to save and open PDFs automatically. Instead, it uses the Firefox PDF viewer - which has improved, but it is not what I would like. I have reset my handlers.json along with trying to force it via about:config. Nothing is working, and it is a hassle.

I used lightspeed POS program. We have specialized forms that print out for us created by a third-party developer working with light speed. A few months back you updated Firefox and it changed our printing where the forms do not print exactly like before. Can this be fixed by you?

At one point earlier this week, I had to sign out of all but one of my google accounts to get a link for a remote meeting to work. Afterward, when I visited youtube, it logged me in under that google account, which is not the one I use for browsing on my own time; I logged out, then, when I tried to log in under the proper account, google/youtube thought erroneously that I had set a passkey, and it and my password manager fought. I fixed the conflict (deleted the unset passkey). Then Youtube stopped letting me log in; no matter what, I get sent to www.youtube.com/oops

Initially, this error effected youtube login on all every browser I use. Clearing the cache and history on those, after having fixed the password issue, fixed the problem on them. Firefox, however, is refusing every fix.

I have cleared the cache, the history, going back to 'Everything.' I uninstalled and reinstalled the browser. I have disabled all add-ons and enhanced tracking. I have gone into the advanced configuration settings for firefox and deleted the cookie files for my profile. Youtube and Google are ON my security whitelist. I've tried "forget about this site." I've tried private browsing after first clearing the cache and history, "forget about this site", and after deleting the cookie sqfiles.

It has been days, and I am going in circles! Can anyone please help me?

After a recent update - I can no longer copy a title from an article and get the full URL to paste in OneNote.

For example with this article - If copied it and pasted it in OneNote it would appear this way

How to Link Notes in OneNote (2026) From <https://www.usecarly.com/blog/how-to-link-notes-in-onenote/>

But now I get this:

How to Link Notes in OneNote (2026) From <https://www.usecarly.com>

I made no changes to OneNote and in settings there: Include link to source when pasting from the Web is checked.

This function is working in Chrome as usual. But no longer in Firefox.

What setting can I change?

Thank you

I restarted my computer, and when FF loaded all the tabs across the top where weirdly blank. I could see that there were tabs but no info. I restarted FF and then there were no tabs. Then I looked to history to restore previous session, and nothing. I've gone through all the various methods I can find about restoring sessions, and there are no sessions. See attached image. Session restore can not find a previous session. When looking for backup files, and using session scrounger https://www.jeffersonscher.com/ffu/scrounger.html I get a few tabs but nothing from my my most recent browsing. I had 28 tabs open, some in groups, and all of it is gone. I've had issues with losing tabs before but always got it back with the session scrounger, and now I can't find anything. What is going on?

For some reason, Firefox is all messed up . Happened suddenly. Some sites are blocked and says " ⚠ Firefox’s Enhanced Tracking Protection (Strict Mode) is known to cause issues on x.com"

But I'm not using Strict mode. Standard is set.

Or Malewarebytes will block the site and I have to click Continue.

Or in Yahoo.com, Yahoo is written in big black letters on top, and as I scroll down, there's nothing but empty boxes, all on a white background.

No, this is not happening on Chrome. All is normal.

What is going on?

So i reset my pc. And i saved a backup(BU1) of Firefox. But every time I try to restore my original backup(BU1), it keeps showing incorrect password. I know it's not but. I did find a workaround from the support page. I made a new backup(BU2). and took BU2s name and gave it to the original backup(BU1). I then replaced BU2 with BU1 in the new backup folder. But it is still asking me for a password. And from what I've read it should be using BU2s password. its not. what do I do? i can no longer access the original firefox because my windows account has been reset. What's even more annoying? I still have all of my passwords and all of my bank details. Without the back up. Because my phone and computer are synced. So I didn't even need to put a password on my PC backup. But I do need my tab groups. Any help would be much appreciated.
