Hello All -

Over the years I have saved many bookmarks across several different devices. Therefore the bookmarks vary between devices. Is there any way that I can tidy up my bookmarks, deleting many of them, on my main machine and then have all the other devices Synch to that list only?

I have tried deleting ALL the bookmarks on the "subsidiary" devices and then synched them but that didn't work. I think I'm asking whether one device can be made the "master" for all the others to Synch to that one and none of the others.

Hope that's reasonably clear.

Thanks,

Ian.

I did a new Windows 10 install yesterday. I then added my favourite apps.

When I got Firefox installed, adjusted the settings and added my extensions (most of which I've used for years), I found a glitch.

The icons for AdBlocker Ultimate and LastPass do not show up in the Customize Toolbar menu. I keep both of these on my toolbar in the past.

I've tried restarting Firefox several times and, finally, tried running it in Troubleshoot Mode. The last, it seems, doesn't allow the use of extension.

So ... please help!

I have an extension I use on my Raspberry Pi media box which locks youtube videos to a selected resolution. On the Pi, this is very useful, as it wants to automatically change to lower resolutions when the resolution is set to "auto". However, on my desktop, this extension causes youtube to not respond to the spacebar properly (it requires two presses to change the pause state). These two browsers are both signed in to the same profile, so when I enable the extension for the Pi, it enables it on my desktop, and when I disable it on the desktop, it disables it on the Pi. Is there any way to have the extension enabled on one browser and disabled on another without using separate profiles? desktop: windows 10, firefox 142.0.1 Pi: raspbian, firefox 141.0

Hello everyone,

Like most of you, I'm aggressively attacked by advertising new tabs.

I'd like to have this: my tabs static, no movement, all fixed sizes, and no new tabs on redirects. If I need a new tab, I manually click the "+".-sign.

Fox tries to fit all tabs in, at the same time.

What I have tried so far is not working:

1. pinned tabs always get un-pinned at restart

2. pop-ups are stopped in Firefox own Settings

3. my settings in about:config: browser.uidensity = 0 browser.tabs.animate = false browser.tabs.tabmanager.enabled = false browser.tabs.allowTabDetach = false browser.tabs.tabMinWidth = 68 px dom.popup_allowed_events = False browser.tabs.loadInBackground = false services.sync.prefs.sync.browser.tabs.loadInBackground = false accessibility.blockautorefresh = false services.sync.prefs.sync.accessibility.blockautorefresh = false toolkit.tabbox.switchByScrolling = False browser.link.open_newwindow = 2 browser.link.open_newwindow.override.external = 3

Tabs still move, change size, and unwanted ones appear. :/

What settings should I change, add, or remove? Anyone more proficient than me, in about:config-programming?

Cheers!

I can't open Threads.com or Threads.net if the Facebook container extension is turned on. If I shut it off, Threads loads fine. If I'm already on Threads and turn on the extension is goes back to the Threads page with just the symbol and I can't use it. Can't sign in through Instagram or through history, either. Is there a work around for this?

Trying to load https://www.fire.ca.gov/incidents and it does NOT load completely, which it did before all of the upgrades... have to use chrome to view the site.

I am using the Firefox browser on my iMac. Suddenly, I am not able to 'sign in' or access pages of common websites. I am getting blank pages or pages with the ever-circling ball when trying to access websites, like homedepot.com, shutterfly.com, etc. I can access them via safari.

I have gone through the Troubleshooting steps, have Uninstalled Firefox and Reinstalled, etc. What is happening with my browser?

I am on a MacBook Air using 142.0.1 (aarch64) and some websites like Amazon.com and Google News are displaying a mobile view, even though I am on desktop. A shift reload causes the desktop view to be displayed, but subsequent clicks lead to reverting to the mobile view.

Hello,

I have several PC;s but all suffer on occasion absurdly slow performance when a Firefox update is released.

I may be wrong but it appears there are too many of these processes running, I tried changing the value in " about:config " but Firefox defaults the value back to " 12 " when the browser is restarted.

" app.normandy.migrationsApplied 12 "

The below details are from a small, new cube pc that runs great, it is slow but does perform well, even previously just the other day running multiple Live Youtube streams with no issues, until now. :)

Any help would be great. Thank you!!!

Hello there, I usually use Firefox as my browser to access my Gmail account. For some reason, I am not able to open up gmail. I put in gmail and it shows in the search bar the following informaiton--mail.google.com/mail/u/0/#inbox . NOthing else happens, no gmail account opens up. Please help.

After updating to v142.0.1 the Extension icons on the Address Bar and the bookmarks on the Bookmarks Toolbar were not showing. Most of the Extension icons are now showing, as is an empty Bookmarks toolbar.

The bookmarks are till available in the Library => Bookmarks Toolbar but not showing in the toolbar.

A similar issue is raised in the Forum but seems to be for a different version of Firefox, where the menu items referred to are not the same as v142.

Closing and re-opening Firefox only shows the same problem. When a tab is opened and the URL is saved to Bookmarks Toolbar, it appears in the Library but not in the toolbar, which remains empty.

Is it possible to remove the block on bookmarks showing on the Bookmarks Toolbar?

I tried to reach the following adress: https://www.itu.int/harmful-interference-to-rnss/ and I received this message on my browser: 400 Bad Request -Request Header Or Cookie Too Large

When I tried from a different browser it was accessible.

I edited a video on my MacBook Air M3 (8GB/256GB) using QuickTime Player and replaced the old video file in my Next.js project folder. After pushing the updated code to AWS Amplify, the website displays the new video correctly in Chrome. However, in Firefox, it still shows the old video with a watermark.

At first, I thought it might be a caching issue, so I disabled the cache in Firefox, but the problem persisted. To troubleshoot further, I ran the Next.js project locally and tested it again in Firefox at localhost:3000. Surprisingly, Firefox still displayed the old video with the watermark, confirming that caching is not the issue.

Can anybody explain me the issue Website Link Video of the issue Video of the link

You can see a Freepik logo appearing over the video in Firefox, but it doesn’t appear in other browsers.

Some extra info to help you 1. This glitch occurs in all OS {windows , mac , linux} 2. I tried to test in whole new devices it occurs on those devices also

for some weeks now, Firefox (latest, in Windows) crashes, or says 'not closed properly' and shows (usually) 12 'instances' in Task Manager when only one tab has been opened. I'm not techie, and need clear advice. Can anyone help please? Hugh, UK

When I try to sign in to my icloud account the account authorization won't pop up at all. I've tried restarting my pc and everything. I'm using Fedora Linux version 42 Workstation edition.

I was not sure what topic/heading to put my question under, but problem occurred like this:

A student organization within my University sent me and email concerning a petition. This is all very legit. But when clicking on the link to see and sign the petition, I got this:

"Application error: a client-side exception has occurred (see the browser console for more information)".

I wonder if this is an EXACT problem you know very well that has to do precise individual account settings, OR could also be linked my status with the University? (I'm a twice Alumni, but am now "lapsed" from my third degree -didn't take a course in "X" no. of semesters- so blocked from registration... And what else)? Maybe this site "is instructed" not open in browser if I'm not a current paying customer of the University?

I don't get it. Links acquired from safe sites, here doubly safe since coming from a legit University address AND safe to come in my email inbox go though like 99% of the time... First I see of this automatic message. I might have change a Mozilla setting SINCE that makes it worse, but I don't understand the original error. I tried to cut and paste in the address bar but didn't help be get answers (didn't see page this way either). Why is it a "my side" problem, why do they say it's an"exception" error, and what is the browser's "console? One's Mozilla acount's home?THANKS FOR CLEARING THIS UP GUYS : )
