We recently update Firefox with version 138.0 and now getting the message "Gah. Your tab just crashed" when opening the browser.

We attempted to update and install version 138.0.1 only resulting with the same error. We also found and attempted the following all resulting with the same error: - change the about:config page for settings to false for both browser.tabs.remote.autostart and browser.tabs.remote.autostart.2

- clear browser cache.

- enable Temporary Mode in the Help menu. This appears to fix the problem but only for the current browser session. When a new Firefox window is opened, the error reappears.

What is needed to resolve this error or is there a way to permanently enable Temporary Mode or some similar setting? Thanks for all your help with this.

I understand that in previous versions, there was a preference in about:config that would let me adjust the delay in ms that I would need to hover over a tab until its tab preview is shown. This preference is supposedly located at browser.tabs.cardPreview.delayMs but when I searched for it in about:config it did not show me any results. Any Google searches do not point me in the right direction either. Does anyone know what I could do to adjust this delay anyways?

Attached is an example of the tab preview I'm talking about.

The virtual keyboard on my HP OMNI 10 tablet has begun popping up at every touch of Firefox. This makes it almost impossible to use. Expected/normal behaviour is that when you touch web pages or any app., the keyboard stays out of the way while you move around. When you touch inside a textbox, the keyboard should pop up so you can type. Touch outside the textbox and the keyboard drops down. Now, ( since the start of May 2025 or so, I think), the keyboard pops up every time I touch the Firefox page, anywhere. This makes it almost impossible to use.

For example, on a Youtube video, I touch the video to start playing.... and the keyboard pops up, covering up the video! I have to touch the x to drop the keyboard down again. When I want to rewind or move forward, I touch the video to get the controls to appear and...the keyboard pops up, covering the video. I have to touch the x to drop the keyboard and by then the video controls have timed out and gone away again!

Right now, if I close the keyboard and touch this page outside the textbox, the keyboard pops up.

In Microsoft Edge the behaviour is normal and in an app., like Notepad, the keyboard only pops up if I touch inside Notepad.

By the way, I did all this typing once already but when you said you couldn't read my troubleshooting information automatically, I tried your manual steps, and that took me to another web page. When I came back to this page, all my typing was gone! Very annoying. please don't do that again.

I am starting to use the new utility which allows me to group tabs. But I would like to see only the name of the group and not the whole list. How can I collapse the list of tabs which belong to a group leaving only the group name shown. Then with a click I should be able to see the corresponding list of tabs if I need it. Saving and closing a group is not a solution, as the group disappears from the Sidebar. Thank you for your help. Best regards Ray Ballisti [edited] @bluewin.ch Switzerland

At some point in recent time I started encountering broken websites, and that "http" in their scripts seems like what's causing it. Full error text in the console: Content-Security-Policy: The page’s settings blocked an inline script (script-src-elem) from being executed because it violates the following directive: “script-src http: https:”

what I tried to do to fix this: 1. Disabling https-only mode in settings 2. Disabling all the enabled extensions 3. Tried disabling "enhanced tracking protection" for pages with the errors; and also tried switching tracking protection from strict to standard in the settings 4. Tried checking problematic pages in a new fresh Firefox profile, and they do work there seemingly fine. But I would like to fix the issue for my current profile and understand what's causing it.

Hallo, seit einiger Zeit friert die Seite von " welt.de" ein. Komischerweise nur diese, sonst keine andere Internetseite. Ich habe schon gegoogelt, woran das liegen kann, habe aber nichts gefunden. Gibt es von ihrer Seite hier Tipps, was zu machen wäre ? Grüße Stefan Zintl

Hello I have the latest version of firefox using for windows7 ultimate and since several months is having problem to watch youtube. it has only 15 seconds working and stops. what to do? thks Best nicolas

Whenever i open a page i get a translated version of it, i have to click on the original url button to get the page without the translation. Anyone knows how to deactivated or remove it? I don't have a google translate widget or smh like that.

Started a couple days ago

Youtube works fine for everything, except when i try to watch a video, the rectangle where the video is supposed to be appears black during loading (normal) but then vanish.

checking the console i get a huge error that's just unreadable for me

it doesn't happen on edge, or in private navigation

turning every addon off doesn't fix the issue, and it does it even in "troubleshoot mode"

i haven't "refreshed" because i don't know what kind of data will be lost when i do that

What does this mean? being updated by another instance

Is this why my FF is running godawful slow today?

Pages coming up in 20 to 60 seconds or more instead of in a second or two.

According to this page: https://support.mozilla.org/en-US/kb/keyboard-shortcuts-perform-firefox-tasks-quickly it defines that, when Editing, I should be able to press Home and End to navigate to the start and end of the lines I am on.

Is that an error? I cannot use the Home and End keys at all in this very textarea I am typing in. Command-Left/Command-Right work, but not Home/End.

I have not changed any mappings of my keyboard, and I'm not using any addons. Restarting the browser in troubleshoot mode does not change the behavior.

I've read innumerable posts about this saying to remap it to Command-Left, but I don't want to do that. I want Home to scroll to the top of the page when I am browsing, and to go to the beginning of the line when typing. This is the behavior on Windows, and it should be consistent across versions. If I remap it, then the Home key goes Back a page, which is terrible.

Also no I'm not in caret mode.

Dear Mozilla,

How do I change the content that is sent to my home landing page when I launch Firefox. 98% of the content is from fake news sources that are wildly inaccurate and just plain not true. This includes sources such as Vox, The AP, Reuters, The Guardian, Business Insider, etc. It seems all Mozilla news feed sources literally are the fake news media which remove trust from your organization, and NOT something Mozilla should be promoting. By pushing those stories and content from fake news sources, it literally makes me not trust Mozilla's intent or objectives.

I have an quite annoying( disturbing) issue related to your browser. The problem is that Firefox is stuck into Desktop mode.

Since I have an Samsung Galaxy Tab S9Fe ( SM-X516BEE). However I've never experienced it on previous versions ( below 120-30 something). My pervious version is: 138.0.2

Not only that all of my serach results are the same as on PC( since Android is LINUX based), bus also that many pages are opened as if they were on PC. But as well that the graphics is completly wierd.

However I have already Deactivated Desctop mode- but however it's still stuck in Desktop mode.

So my vonclution is that Samsung devices( Tablets) make it easy for itself and make it equal to LINUX/ UBUTNU.

So it also sems that all versions published on Google Play= to Desktop( PC/ LINUX). So please get rid of this annoying stuff and publish an regular mobile version.
