I've got Reading the full Article on GROUP TABS that has been released yesterday on My Firefox it Got Update and Installed But I just couldn't found the "Add to the Group option when I click right at any of my tab" + If I drag over one on Another Tab it just got replaced like they substitute their Places No BOX Border line Shows No Group Created NOTHING. I'm a Nearly 6 Year Old Firefox User I NEEDED that FEATURE SO BADLY PLEASE FIX it SOMEHOW. ThAnks Regards: Loyal USer

the tab groups feature doesn't work. WHen i drag one tab onto another, nothing happens, other than the tabs go back and forth. Can't put one tab over another and no group is created.

Previously I could change the color of ONLY visited links. 138 broke that ability and replaced it with a contrast setting that changes every kind of link color and the page background color/design too. This totally stinks and makes the visited web pages look terrible and hard to read too.

Is there a way to set FF so that ONLY visited link colors can be changed to the preferred one?

I had a Firefox update yesterday, April 29th. Since then, my Bookmarks sidebar no longer opens automatically when I open my Firefox browser. I have to go to the sidebar icon at the upper right of my screen to open the Bookmarks. I went to my settings, and the box for automatic opening was not checked. I checked the box, and it still does not function. Any ideas as to what the problem is, and what the solution could be?

I'm running v138.0.1, but the ability to group tabs that was supposedly introduced in v137 is completely absent from my browser. I can neither drag tabs onto another to create a group, nor create groups by right clicking on a tab. What's up with that?

MY FF recently updated to version 1380.1 (64bits) and my Sidebar Bookmarks are gone. That is I have to manually put them back every time I now start FF. I want them to always show when I start FF. When I need extra screen space, I would click the X and they'd disappear for that session. And when I was done, I'd click on View - Bookmarks they'd be reinstalled. And when I shut FF down and returned later, they'd be right there where I need them.

My question is, how do I get back to that setup?

Just recently, the Bookmarks sidebar quit appearing automatically when I opened Firefox. In each new window, it can be selected manually.

I posted this thread under "Privacy and Security" because other threads on the Internet (some quite old) say this issue can be fixed by changing the Browsing history settings. I tried that, but got a strange result: the Bookmarks sidebar did appear automatically, but the webpage I was on would not display any images embedded in the page. And then I wondered: why must I eliminate Browsing History just to automatically display my bookmarks?

Any help would be deeply appreciated.

I use several browsers and when it comes to functionality I consider FFox to be the best however with 1 major drawback - it's speed / lag issues which is why I stopped using it as my primary browser and only as secondary one

I can have 2 different Chromium based browsers open simultaneously and while this impacts the performance somewhat if I open Firefox and another browser responsiveness grinds to a halt (sometimes even crashes)

Even just starting Firefox by itself takes 5x as long as other browsers

So I'm wondering is Firefox just more resource intensive or is there something wrong with my setup?

The main difference between my Firefox install and my other browsers is the number of Bookmarks (10000s) due to me having it installed for much longer so is it possible for a large number of Bookmarks to slow the browser down even when not open ?

Other possible causes I read elsewhere are 'Cookies and site data' (currently around 50mb)

I clear the 'Temporary cached files' & 'Browsing history' on regular basis so they shouldn't be an issue

The add-ons I have installed are NoScript , Ublock Origin & Firefox Color

In regards to troubleshooting is it possible to install a 2nd install on the same system simultaneously without overwriting the current one ?

Thanks

After Update to 138.0 my sideabar (bookmarks) is away. I can reactivate the sidebar on the left side as wished. But when I open a new Firefos Window or Tab the sidebar ist away again. What have they done, mozilla ?? How can I get mey bookmarks ALWAYS shown on left side of any Window or tab ?

Despite Tab Groups not yet being "rolled out" in Australia, I am wondering if "Container Tabs" will still be Supported (in the following ways):

1. Will Container Tabs still be able to be used effectively in concurrence with Tab Groups? 2. Is it planned that Tab Groups is being developed to replace Container Tabs? 3. If one will be able to use Container Tabs concurrently with Tab Groups, can different Container Tabs Types be split over different Tab Groups? 4. Is it planned that Tab Groups will supersede Container Tabs in terms of Protection, Privacy, etc.....? 5. Will Tab Groups be able to be put to sleep/hibernate in order that Firefox "speed/memory" is not effected?

Whilst on the subject of Tab Groups and Container Tabs: 6. Up until a few updates ago, when the mouse was hovered over a Container Tab, a dialogue box would indicate: the Tab Subject, Site Identity and Container Tab Type. Please bring back the Container Tab Type when the mouse hovers over a Container Tab..! 7. When this (Valuable) information was ceased, the only way to get similar information - namely the Container Tab Type - has been to use the: List all tabs icon {tab icon 2} at the Right hand end of the toolbar. It is a blessing that this was not changed, but still a bit of a nuisance to check them both! Why is this an issue you may well ask? - I am sure I am not the only Firefox user (Forever) - with memory decline!

Thanx

Hello,

I recently updated my Firefox browser to the latest version, 138.0.1 (64-bit), on Windows.

After the update, I noticed that when playing videos in fullscreen mode (for example, on YouTube or other video websites), the Windows taskbar (the bar at the bottom of the screen with the Start menu icon) does not hide automatically. This is affecting my fullscreen viewing experience.

Before updating to version 138.0.1, the Windows taskbar would hide correctly when entering fullscreen video.

I was wondering if anyone else has encountered a similar issue with the Windows taskbar not hiding, or if there are any suggested solutions to help resolve this problem.

Thank you for your help!

I got an email supposedly from breach-alerts@mozilla.com that claims there are currently 3 data breaches and has this link to resolve: https://blrv1ly5.r.us-west-2.awstrack.me/L0/https:%2F%2Fmonitor.mozilla.org%2Fuser%2Fdashboard%2Faction-needed%3Futm_source=monitor-product%26utm_medium=product-email%26utm_campaign=monthly-report-free-us-scan-no-exp-yes-breach-resolved-no%26utm_content=resolve-exposures-us/1/01010195ceba1024-6e3f74fe-119a-4e2e-9033-398671a830d9-000000/DDeGOTLjROOXCCk2fJvXJbdefc4=419

This seems like a phishing email, is it legit? Should I find another browser?

the tab groups page i was shown by firefox says i should be able to group my tabs starting at the latest yesterday but my tabs still just move out of the way and refuse to group. i found container groups but they work nothing like the page showed. i have firefox version 138 and the tab groups was starting to be roled out on 137

I have the most recent update and have been excited about tab groups, but it's still not working on mine. I thought the update would be available to all as of May 6, 2025. Is this happening to anyone else?

‘New update for Firefox removed my bookmark menu from side bar. When I open FIrefox, my bookmarks are gone, but a one inch vertical, useless space appears. Please help.’ for ‘Firefox’

When accessing Outlook (https://outlook.office.com) using Firefox ESR version 128.9.0 and attempting to download a file attached to an email, the string 'UTF-8' is automatically inserted at the beginning of the file name, which is causing issues. This phenomenon does not occur with other browsers such as Edge or Chrome.

Is there a way to solve this problem?
