Whenever i send a Tab from any Device to a Linux Desktop, the Linux Desktop is almost guaranteed to freeze. It doesn’t matter if that Linux Desktop is my "Dingus" PC with 2GB RAM and Wayland, or my "Workstation" PC with 16GB RAM and X11. On both Desktops, Firefox runs smoothly until it gets sent a Tab from another Device, then the whole Linux Desktop freezes. The Desktop doesn’t slow if i open the Tab on the Desktop in the “Tabs from other Devices” Sidebar instead.

Only my Linux Desktops freeze when they get sent a Tab from another Device. Android doesn’t slow when my Phone gets sent a Tab from another Device.

Today Firefox has suddenly started using ~20% of my CPU capacity, causing my cooling fan to run high most of the time. Since I had been running Firefox v.149.latest, I tried updating to v.150.0, but that made no difference.

It's not Firefox by itself (only Task Manager open) but whenever I open another tab with almost any website (including this one) that CPU usage spikes. What gives?!

Details: Running under Windows 10 Pro (yes, I have installed the ESU package, good until thi8s fall) on a Lenovo P1 Gen 2. Currently running Firefox inside a Sandboxie Pro v1.17.4 sandbox.

Hey everyone!

I just noticed that post FF's 150 update, I can no longer drag and drop folders into my DSM window. This has been a non issue for over 6 years and all of a sudden, poof. I did find that you can still to this on Safari, but long term, Mozilla and Synology need to address this. There's already a post on the Synology fourms about it and I've emailed their Support Team to see what they have to day. Posting this here in case anyone has found a workaround in the Config settings pane.

Thanks! --Brian

Firefox 150.0.1 Ubuntu 22.04

Problem: When downloading a file from a web page, the list of files and folders in the Download Panel are sorted such that file names and folder names are intermingled, rather than the "standard" folders first, then files.

Discussion: This problem has been happening for a bit now (probably 2 - 3 months or more). Unfortunately, I don't recall exactly which version of Firefox this originally showed up in. At some point recently, the default sort for the Download Panel changed, so that instead of listing folders at the top of the list of download targets, then listing files, now all items are interspersed. For example, previously selecting to download a file from a web page would give the Download Panel contents as:

AFolder BFolder CFolder AFile.txt BFile.pdf CFile.jpg

Now, the list presents as:

AFile.txt AFolder BFile.pdf BFolder CFile.jpb CFolder

I would like to go back to the previous sorting behavior, but I cannot find a way to do this. I have searched the Mozilla help articles without turning up relevant information, and I have searched the internet for web sites that might list relevant information, but either the information I am seeking is not out there (unlikely) or I am not coming up with search terms that locate the information (much more likely).

I am not even 100% sure that this is a Firefox problem (it is within the bounds of possibility that it is an OS problem), but none of my other regularly used programs show the symptom, so it would seem odd to me for it to be something other than a Firefox problem.

I would appreciate any pointers (web pages, help articles, or even just "change this in about:config) on how to resolve this.

ie every time I closed it it would reopen- 14 times when I am trying to read my emails yesterday and 6 today. but I thought it was my internet security causing the problem. I kept getting notification that a certain site was attempting to use my system,. The worst thing was it kept flashing on my screen and wouldn't go away, There was no clue who öwned it, my security or Mozilla's. It was finally resolved by contacting my computer guy, but we never identified the source. the site that was being blocked started with pssst.........com, or something similar but it was driving me mad trying to get it off the screen. If this happens again, how do I get rid or stop the continual notifications? Of course I have nothing to show you as I have since deleted it, sorry. as I was just relieved to see it gone.

Thank you Angela Johnson

Hello. I have a question regarding a problem with exporting files in Firefox. For about four days now, when I try to export files in Firefox, it fails. I've looked into it, but haven't been able to find a solution. Could you please give me some advice? I've tried various things within my capabilities, but nothing has worked. Firefox 150.0.1 64bit

Hi,

I shared a lot of important tabs to my laptop (using the firefox built-in share/send to other device button), upon starting it, they seemed to arrive just fine and opened on my laptop, however I accidentally clicked to "history"->"restore last session", which made this firefox window go away and all my sent tabs seem lost.

Is there any way to get them back? Any type of log?

I tried the following already: - Looking through History (they do not appear there at all) - Looking at recently closed tabs (there aren't any listed) - checking synced tabs window (did not contain the ones I sent from my phone to my laptop) - checked session recovery files ( none of my synced tabs seem to have gotten stored into that session recovery file)

So is there any other log or place I can look at? I refuse to believe that this is not saved anywhere? Or on mozilla servers at least? Can support help me?

Thanks for any ideas!

EDIT: I found this, may is something similar: https://connect.mozilla.org/t5/ideas/send-tabs-log/idi-p/15640

Over the past few weeks, my typing is continually being interrupted. It did this a few years back, but this is getting very annoying and I am soon to switch browsers if not fixed. BTW on any machine using Firefox, this is happening

macOS Tahoe; 26.4.1 Firefox 150.0.1

I keep most of my bookmarks under the "Bookmarks Toolbar"; I have quite a few of them.

I've always enjoyed the ease and utility of the "Add Folder..." menu item in "Manage Bookmarks", but now it fails on each and every attempt to add a new folder! For example, if I select a folder under "Bookmarks Toolbar", right click that folder, and select the "Add new folder..." item from the drop-down menu Firefox simply "freezes up" - becomes totally non-responsive (spinning beach ball!).

The only way I've been able to recover is using the macOS "Activity Monitor" to "Force Quit" Firefox! If I repeat the "Add Folder..." process described above - Firefox "freezes up" again. I've tried re-booting, and that doesn't cure the problem.

Without trying to confuse the primary issue, I have noticed other "bad behavior" from Firefox:

1. 1. Firefox "disappears" from the menu bar regularly. I can get it back by moving to another desktop, and returning to the desktop with my Firefox windows. However, it will disappear again in short order.

1. 2. Firefox is very slow loading some of the web pages I visit regularly.

When did this start? It started very recently. I have a new (about two weeks old) MacBook Pro. The "Add Bookmark.." issue began only today, but the other issues I mentioned have been around longer.

This is frustrating... I suspect this is caused by Apple's macOS software, but of course have no way to prove that! And in the "FWIW Column": my Chrome browser has basically the same function and interface for adding folders, and it still functions flawlessly.

I've tried to access each of 3 new TP-Link EAP 770 access points' web interface using current version of Firefox on a Mac and a Windows 11 laptop and I believe there's some security setting blocking the access. Usually, I would receive the warning with an "Advanced" button to allow you to continue to the web interface, but now I only receive a "Looks like there's a Problem with the Site" with a "Try Again" button. I had an older Windows 10 laptop with an older version of Firefox that actually allowed me to access one of the access points, but after the laptop had been online for a few minutes (and updated the Firefox version) my access started to fail again. Any help is appreciated.

Thanks, JB

About a week ago I had printed 2 copies from my Firefox browser. Next time I only needed 1 and changed it. Since then it stays at 2 and no matter what I do it won't go back to one.

How do I fix this?

I recently bought a new laptop running on Windows 11 Pro. All my settings for languages (English GB) in Firefox are the same as my old laptop, which was Windows 10.

On my W11Pro laptop, the translation icon doesn't appear when I highlight a portion of text in a foreign language, whereas it did appear in my old laptop. If I right click on the highlighted text I can access "translate selected text" but nothing happens when I click on that. Translating an entire webpage works fine, it's just the highlighted text that doesn't.

I'm not very technically minded, so any answer will need to be in simple terms! Thanks.

When I press F12 to use the developer tools and try to change the width of the panes by click and drag the divider there now seems to be a limit to the panes width that was not there before. I'm not sure with what version I stated to notice this. I use to be able to drag the right hand panel fairly far over to the left and could take up about 75-80% of the width of the developers window. Now I'm guessing that I'm able to drag the right panel to a max width of 35-40% for some reason. I have not changed anything in the about:config page. I'm not sure why I can't drag the right panel to cover the 75-80% of the window that I had been able to do.

Is there a setting in the developer tools or on the about:config page that sets the max width that the right hand panel can be dragged to the left?

How can I resolve the failure to open because it can't find the XPCOM. I downloaded a new copy but the computer insists on using the older, faulty version to open files and it will not work.

I was trying to do something with my bookmarks yesterday and I must have pushed the wrong icon. Firefox then became unavailable. I'm 88 years old and not fully at home with computer language. I tried Chrome, but it's not available like Firefox.

On all other browsers the drop down menus still show after first use, except in Firefox - where after first use they disappear and you have to go back to Home to re-show them.

I have tried the suggestions give for configuring the site iin Elementor/Wordpress but none have solved the problem and I can only assume the answer lies in Firefox settings.

TIA

When watching twitch and I open another tab, the new tab is very slow to open a web page and sometimes wont open at all just keeps scrolling. Any suggestions how to solve this problem?? I tried with Opera and it doesnt have that problem?? Dont want to give up on Firefox as I like it the most. Any help much appreciated.
