Ondersteuningsforum voor Firefox

It's so frustrating that the keyboard shortcut for closing tabs is right beside the one to quit Firefox. I've lost countless hours because of this, and it's so easy to accidentally do. Is there a way to keep this from happening? A simple "Are you sure" confirmation dialog would be great, or I really like the Chrome "hold command-Q" to exit feature. This seemingly simple function is proving extremely difficult to accomplish.

Yes, I'm aware of session restore, but (1) It does not preserve my window arrangement. I use multiple desktops for various tasks, and they each have related browser windows. (2) I need to see webpages exactly as they were when I opened them. Sessions expire, dynamic pages are refreshed, content is removed etc. That is all lost.

I do not want to disable session restore completely. It can still be useful. But, I do not want to trigger session restore automatically every time. Manual activation is ideal.

regarding: "browser.tabs.warnOnClose" I do not want a warning for closing multiple tabs. I often have many windows open and that warning gets annoying. It also doesn't prevent me from accidentally quitting when I only have one tab open.

I tried setting browser.warnOnQuit to true, but it's ignored.

I simply want a confirmation when I use the keyboard shortcut to QUIT. That's it. No side effects. Can Firefox do this?

I don't want to have to reconfigure my settings every time the pictures are gone. It seems silly but it just looks wrong to me and I like seeing the pictures so that I know at a glance which top site is which. How can I fix this problem of my browser not displaying the images in the top sites correctly after closing the browser? Thank you!

FF with no tabs, add-ons or browsers open establishes a connection to the following

104.16.248.249:https (ESTABLISHED) ec2-52-27-98-21.us-west-2.compute.amazonaws.com:https (ESTABLISHED)

Why is this occurring?

As an example, I search kijiji for kid's bicycles. It shows me the various ads but the box where the photo should be is empty. This happens with similar search results as well - words but no pictures. Have been using Firefox for many years. Why is this happening now. Using iMac with Catalina latest version.

Hi: Youtube has suddenly stopped working on my Firefox browser for my Mac. It works on Chrome, and on my Firefox app on my iPhone. It was working fine a couple a days ago. I disabled the only extension I had as well as the "Use hardware acceleration" to no avail. Any ideas?

Firefox on MacOS Catalina fails to save/restore tabs, whether pinned or otherwise, after shutdown.

I have extensions: Bitwarden DuckDuckGo Privacy Amazon smile sponsor redirect Amazon Unsponsored YouTube Sponsor block

Tried it with and without these running and FF fails to save my tabs, regardless of shutting down the browser or the OS. This does not occur on Win10 or my Linux distros. I've been trawling forums and help pages and the Interweb casually for weeks now, without success, but getting quite frustrated now; so posting this as a last resort. Thanks in advance of any suggestions.

Ever since the latest update to Firefox I can't scroll thru my Bookmarks Sidebar. When I try it does all kinds of random scrolling actions, flashing, scrolling randomly.....etc. It is a mess.

I have other software with sidebars that work fine.

Since yesterday, August 4, my Gmail acccount is getting bombarded with spam. Why is this happening and how can I stop it? I have put the strongest controls on Firefox. Thanks.

I have two issues that seem to be related. I have a Mac (Catalina 10.15.6) and I use the Firefox browser. I've adjusted my preferences and selected Google as my Default Search Engine. My issue is that when I "Quit" Firefox and open it again my Default Search Engine gets changed to the Browser Default (which seems to be Yahoo but isn't listed as that). I then have to go back to my preferences and change the setting. I've tried Removing all the Search Engines in the One-Click Search Engine list except for Google but when my settings get changed, the Browser Default search engine pops back up in that list. My related issue is that I'll be in the middle of doing things in the Firefox Browser when it will suddenly close. I don't get a warning nor a crash report. It's just suddenly closed as if I "Quit" my browser. When this happens, my Search Engine settings change as well.

To fix this issue I've tried changing settings, tried uninstalling/deleting the Firefox application and reinstalling it from the Firefox website using a different browser. None of these attempts fix these issues. I'm getting quite frustrated with this glitch. I'm a relatively new Mac user so am not as familiar with how to troubleshoot things as deeply as I do in the PC world. I didn't have these issues with Firefox on other OS's (Ubuntu & Windows). Is there a fix that doesn't involve me installing any other external apps?

Whenever we encounter a Captcha on a site, Firefox does not display it so we can never make contact. Also, we use a site Duolingo for learning a language. It no longer works with Firefox. It works fine with Safari. Can anyone help us in plain English? We are computer nerds.

using the CTRL+TAB to show open thumbnails tabs visually is a great feature firefox have over other browsers and what encouraged me to leave chrome. have only 6 inst very effective - this needs to be dynamic (for at least 10-15 tabs) and going over the web is seems a lot of people asked this feature.

Is there a way to change this? if not where can I ask a feature request?

Hi all,

I am trying to customize my Firefox on Mac because the tabs on top interfere with the menu bar, thus I only want tree-style tab extension to work on the side, with the tabs on top disabled.

I followed this thread: https://support.mozilla.org/en-US/questions/1184674#answer-1028260 as well as this clear guide on how to create userChrome.css: https://www.userchrome.org/how-create-userchrome-css.html When I tried to restart the browser, I seemed to have been logged out of my profile, with all customization gone and a standard white (instead of black) menu. I deleted the chrome folder and it is normal again now.

I suspect the userChrome.css file should contain more than just the one line I tried to add: #tabbrowser-tabs { visibility: collapse !important; } ; Is there any location where I can copy my current intra-browser customization into the userChrome.css file?

Can't empty Firefox cache completely (started today, 08-04-2020) I always empty the cache when I move from one subject to another in FF browser. Cache always empties to 0.

Beginning today, cache empties only down to 164kb. Cannot clear it of that durned 164kb !

Stumped & Puzzled

I am trying to keep a work (Windows 10) and home computer (Mac/Mojave) in sync for my Firefox settings. I have long been on beta update channel at home (now 80.0b3) but work machine is locked down to release version only (not sure which one that is).

I get the following error when I try to sync or open a release channel version of Firefox

"You've launched an older version of Firefox.

Using an older version of Firefox can corrupt bookmarks and browsing history already saved to an existing Firefox profile. To protect your information, create a new profile for this version of Firefox."

This error dialog offers no options for 'override'.

I need my current user profile to work across platforms and on release channel. I have customizations that I cannot recreate because FF made it too hard to find out how to recreated long-ago and necessary modifications (like killing that bleeping 'throbbing' tab slider that I cannot cope with....and others I don't even know how to describe.

I don't care about bookmarks and browsing history--I never save history and I know how to export, save, and reimport bookmarks.

I care only about my about:config, userchrome and prefs.js and the like.

How can I get around this BUG?

And: am I the only one who thinks the throbbing slider on the loading tabs is the creation of the devil? I can't avoid getting distracted by it--the visual noise is intolerable especially in a work environment.

I use Firefox for my office, and there are several URLs internal to my company that work with a single word.

For example: "xyz/12345" is the same as "http://xyz.company.com/12345" which opens the resource 12345.

This used to work absolutely fine until the latest update.

Current: 78.0.1 (64-bit) on MAC OS 10.15.5

Now, xyz/12345 searches google instead of navigating to the website. I do still need google search on the browser bar, as I use it frequently as well.

Having to type out http://xyz/12345 is an overhead that I would like to avoid.

Please suggest if there are any workarounds that could be used to get this working again.

Hi,

I am on a MacOS Firefox v79.0 16 bit and I used to have the Params tab in the Network section of the Developer Tools that shows the GET/POST parameters.

It suddenly went missing after some update this year. May I know how can I get it back?
