FireFox Mozila 115.13esr 64 bit, Suddenly hang while working on 2 to 3 tabs respectively. And In taskmanager It consumes alot of memory and dump the whole system speed.

How can I disable any non essentials background usage or make it light for window 7 with get no load.

Thankyou!

For the past week links i click on will randomly not open in the tab nor will it be able to refresh(its greyed out), I'll have to close the tab and click again and it will usually load that time.

I have already cleared the cache and cookies, refreshed AND re-installed Firefox and this problem is still occurring.

I have a problem with opening multiple tabs and displaying graphics on pages. I have to verify about 2000 pages and I open 10-20 each time. unfortunately, graphics are not displayed on them - written content and formatting are loaded, but without graphics. When I open pages one at a time, this problem does not occur. When I open 5 pages at once, at least one of them does not have any graphics loaded, the rest have them. How to make graphics load like in Chrome - on all open tabs en masse?

hello, running win11, ff128. the tabs are currently located at the top of the window, just above the address bar.

how can the tab bar be relocated to the bottom of the screen / window directly above the taskbar?

a long time ago there was an extension "tabmixplus" that gave the option of locating the tabs anywhere, but firefox updates broke it. i then found a userchrome script that performed the desired action, but ff updates broke it.

advice? solution? userchrome script? extension? thanks

Hello, I used to have Microsoft Teams as a pinned tab (in fact I think it was my first pinned tab), which I no longer need as I now have the Teams app on my computer. I have tried unpinning the Teams tab but whenever I close & reopen Firefox, it reappears - it doesn't show up initially, but will pop up 5-10 seconds after Firefox starts (my other pinned tabs show up straight away) - so I have to close it each time. Not a big issue I know but kinda annoying - any suggestions/solutions?

This is a new problem, I've only had on this new device, previously when closing tabs, they wouldn't move till the mouse had been moved away.

Now, they move in the fraction of a second before the tab closes, which frequently means a different tab is now under the mouse and then that tab that I didn't want to close, closes.

I'm not sure what the problem was since I imported my profile from my previous device. Maybe there's something in the config that I can change to fix this?

Thanks!

It won't save open tabs when I close Firefox. Each time I have to go to: Setting>>History>>Recently closed windows. In General settings it's ticked Open previous windows and tabs. I already tried to turn off all extensions.

Is there a functionality to view Tabs Side-by-Side, or Vertical yet? Or is there a plan for it; similar to the recent version of Edge Chromium? I have read several questions; and their work-around solutions of using a side bar or sing two windows and arranging them side-by-side. Neither functionality offers synchronized scrolling. I used Tile Tabs or We Tabs add-on in the past which was great.

The pdf gets overwritten by the new text when it is scrolled down or up and the whole pdf becomes messy. I have attached an image showing the same. The terminal gets into the background of the pdf and any other application that is opened on the screen.

I have an issue with firefox.If I click the tab ,it should move to next field.when I click up /down arrow in drop down field ,it is moving to next field without clicking the tab itself..it's happening only in Firefox ,If I try in other browsers like chrome ,IE it works. Is this issue related to extension or browser version or should correct it in javascript code.what should I do??

OS Version: Windows 11 Home, 23H2 Firefox Version: 127.0.2

I have several virtual desktops: Desktop 1, 2, 3 and 4. Case 1: Assume that there is at least one opening Firefox window in any virtual desktop. And, if I try to open a new window in Desktop x (x = 1, ..., 4), it will appears in Desktop x as expected. Case 2: Assume that there are currently no opening Firefox windows in any virtual desktop. And, if I try to open a new window in Desktop 2 or 3 or 4, it will only appears in Desktop 1.

Hi firefox community,

I am using Firefox version 127.0.2 as my main browser on MacOS Sonoma 14.5. For the past few months, when using Firefox in Mac's full-screen mode, I've been experiencing an issue where one of the multiple open tabs unexpectedly displays in a separate window the moment I click on it.

This behavior didn't occur previously, and I believe it started happening about 3 months ago. It doesn't happen every time, but occurs a few times a day when I least expect it, making it difficult to identify the specific conditions that trigger it. I use a Magic Trackpad, and after switching to full-screen using the three-finger gesture, the moment I try to activate a specific tab, that tab alone displays as a separate window in full-screen mode.

Is it possible that a Firefox version update has changed this behavior? If this is a Firefox issue, is there a way to capture debug logs to have the developers investigate it?

Alternatively, if there's an option to prevent tabs from opening in new separate windows, that would be an effective workaround. Could you please let me know if such an option exists?

Best regards,
