Hello: FF dev 150b5,w11p. With this v 150 there's a new irritant that I would like to stop, please. That's the sudden (starting w/v150 again) appearance on lower L corner, of a popup window, which may be interactive. That is, this thing is so new I can't say more about it except that I didn't change anything to make this thing appear, & this didn't happen in prev.versions.

I looked in settings & the only thing on keyword "popup" goes to, in "search results", is: "block popups & 3rd party redirects." I already had that choice checked from previous versions (that is, do block). But this new popup appeared (unasked) anyway.

Is there an extension that will stop these? If so, what keyword(s) do I put into the "search extensions" box to find the extension(s)?

Also, w/this new "wonder" of unasked-for popups -- is this another "coming w/AI" feature I will have to live with?

I did a search here on "popups" before posting,but came up w/nothing relevant.

Thank you.

My bank has recently switched the position of 'online' and 'bank name' in its login URL. How can I delete all history for the old URLs (e.g. Bankname*) without deleting history for all non-bank-related URLs?

I installed Firefox Developer Edition and I am having the following issues, whenever I go to Indeed and I go to a job posting the browser opens up additional tabs without my permission or me doing so. Also the browser does the same in Canvas when I go to my course the browser automatically opens up new tabs without my permission and also me doing so. The Firefox Developer Edition browser update is Firefox Developer Edition is up to date 152.0b7 (64 bit). The following extensions are installed AdBlocker Ultimate, FoxyProxy Basic, Ghostery AdBlocker For Privacy, Malwarebytes Browser Guard, Privacy Badger, and UBlock Origin. This behavior got super annoying and I don't know how to fix it. Any help on how to fix this would be appreciated. My operating system is Windows 11.

Good morning, I'm running Firefox Developer Edition 143.0b6 on Linux Mint 22.1. A couple of weeks ago I noticed that when moving tabs on the left-hand side they'll instantly get locked into an inscrutable and seemingly impossible to fix "pinned mode". Is there a way to turn this off? It is driving me crazy. I've looked through Settings > General > Tabs and about:config and didn't see anything relevant. If anyone has run into this or knows a workaround, I’d be grateful to hear it.

Hello everyone,

I have a problem. I have seen that there have been discussions about this in the past. Unfortunately I have not found a solution and the discussions are all archived.

Now to the problem: Various pages have no favicon in Firefox when I drag them into the bookmark bar as a bookmark. However, when the page is active in the tab, a favicon is visible there.

The problem does not seem to be unique to me. Several people have tested it. It also seems to be a problem in Firefox only. In other browsers, this problem does not occur.

What can website owners do to fix this problem?

Here is an example of a site where I have the problem. www.organspende-register.de

Many thanks in advance. Best regards

I'm using Firefox Developer Edition 132.0b2 (64-bit) and noticed that the only way to open a new tab is to click on the pancake icon and select new tab. The "+" icon in the tab bar is missing.

I also noticed that there is no way to reload the page (especially doing a hard reload). This is a major issue when making updates to websites and wanting to see those edit. Clicking in the address bar and then on enter will reload the page, but does not do a hard reload, so the cached version of the page is displayed, not the updates.

Hello why my firefox installation 1440b6 64 bit on windows 10 do not autocomplete the third field in a form login ..

namely , username and identification password are correctly filled , but the third field (that in my case are named "company ID") would not, it remain empty, and i need to manually fill in each time. Actually this happen only on a one site , but may be because only this site that i use have a three field to fill in the login page...all the others need only password and username

thankyou kind regards klx140

So, forgive me, I'm a little frustrated right now, but I needed to move an Open Tab to it's own window, without the use of my mouse (yes, it's having issues right now), but: I used to do this by tabbing to the TAB in question and pressing <Shift> F10, which opened a context menu with a Move To sub-menu. Now the menu didn't have that option. see pic below. ...Yes, I was able to do the same via, File | New Window, and coping the address to it with Windows cut/paste and <Alt><Tab>. Still I would like to know how to get to the TAB context menu option without the mouse.

The latest update for the beta version 153.0b1 of 6/16/26 has made my theme stop working although it still says enabled. The theme is: ANIMATED Sakura by candelora 🌸 Theme Designed by candelora © 🌸 Animated Apng Theme I'm using Windows 11 on a Lenovo IdeaPad Flex with Firefox as my default browser. I'm an old lady, not tech-enabled in any way. Please help and thanks.

A couple of days ago I noticed that Firefox had started using "Profiles". I do not want a profile. When I wanted to open firefox a window popped up asking me to pick a profile. I deleted my account. Now Firefox will not let me use it because I don't have a "Profile". If I cannot use firefox without a profile, which I never had to do for umpteen years, then I well switch to Chrome.

I just accidentally deleted a day of history, now it has to relearn a bunch of stuff.

Please add support for undo, so that if you do it by accident, you can reverse it.

Hi y'all, when I use firefox DE, there is a bug in which the search bar overlaps with the tabs, after the new release. Is this because I use a custom CSS that reverts the tabs back to the old style? I would really appreciate it if I could still use the old firefox tab style without having my search bar overlapping with the tabs

In May 2025 all browsers should have removed the default styling for the h1 element when it is nested in a sectioning element (article, aside, nav, section). I went into Firefox Dev Editions user-agent style sheet and noticed that the styling for nested h1 elements is still the same. I'm wondering why that is the case, since I was under the impression that all the major browsers had completed make the necessary adjustments at the end of May 2025.

I've been seeing this more and more, but my toolbar will change by itself every restart. The add tab button will shift all the way to the left or not appear, the bookmarks won't appear, etc. I'm not sure what can be causing this, and I saw no way to "save" my current configuration other than pressing the done button upon using the custom toolbar, which I had done every time prior to fix my configuration. Does anybody know why this is occurring, and a possible fix? Thank you

I really enjoy the new sidebar revamp, but I've had an issue with it recently that I haven't been able to find a solution for. Typically, the settings gear is supposed to be situated near the bottom of bar. However, as demonstrated in the attached image, it is at the top near the bookmarks and history buttons. I have tried reinstalling the browser from scratch, turning the sidebar on and off, turning vertical tabs on and off, and even getting rid of my custom CSS theme for a time. None of these have worked. If anyone knows what the root of this issue is, I'd really appreciate the help.

Hello, I am currently using Firefox Beta and I would like to switch to the regular Firefox Release without losing any of my data (browsing history, bookmarks, passwords, add-ons, and settings). I would appreciate guidance on the safest recommended method. Specifically:

Is it safe to install the Release version over Firefox Beta, or could this cause data loss or profile conflicts?

What is the best way to create a full backup of my Firefox profile beforehand?

Should I expect any issues with add-ons after moving from Beta to Release?

Do you recommend enabling Firefox Sync as an additional safeguard, or is a profile backup enough?

In case something goes wrong, what are the recommended recovery steps?

My setup:

Operating System: [windows 10 ]

Thank you for your assistance.

Hi whenever I use my Google account to sign into websites (Google, ebay, YouTube, & anyother sites,) Firefox will become unresponsive, the window containing the tab i was using becomes unresponsive, sort of. - I can't click any open Firefox Tabs, - the red 'Close' radio button is greyed-out, so I can't close any tabs or the window - right-click is unresponsive, so i can't close tabs that way, but Command-W closes the tabs normally, but the others are still unresponsive.

- i can open a new Firefox window (with &/or without Tabs,) which works normally.

- & unrelated, but earlier, Firefox was running really slowly, Youtube videos were slowed down, but audio was normal, and scrolling was slow.
