I have a work and personal profile. On my work profile, when I go to amazon, I see the pricetag icon in the URL bar and it works as expected. However, on my personal profile, it's not showing up at all; no icon, no prompt, it's like it doesn't exist for that profile. I've restarted both profiles, and it still isn't showing up.

I'd prefer to do my shopping on my personal profile, and not my work profile. Any ideas why it's not working on one?

Today I opened Firefox and the tabs were like this. I didn't touch any options in userChrome.css or about:config in months, so I have no idea why it happened (maybe a shortcut or the last update changed something?). How do I go back to a normal height? Thank you kindly for your responses

My browser was just updated today and now my Toolbar Bookmarks are missing from the toolbar. "Most Visited" with a gear is on the left and Other Bookmarks with hardly anything in it is on the far right. I have to go to Bookmarks at the top to access my Toolbar Bookmarks. This is not very handy. I put the bookmarks I need all the time on the toolbar.

Bookmarks toolbar is set to "Always Show". It was fine before the update so...

I often see that some pages take up too much memory. This critically affects the performance of my laptop with 8 GB of memory. However, I was unable to reproduce this behaviour. Now I have caught two web pages.

https://linuxhandbook.com/sort-top-command/ 

and https://www.tutorialspoint.com/how-to-find-number-of-ram-slots-in-linux The first page quickly takes up 1-2GB and continues to drain memory. The maximum usage was 7 GB on a laptop with 16 GB of memory. This behaviour is the same in Firefox and Chrome. The second page quickly takes up 2GB, which is very noticeable on 8GB laptops. Why do these pages take up so much memory? Most importantly, how can you protect yourself from such an unexpected memory consumption?

As described in this thread (https://support.mozilla.org/en-US/questions/1431159#answer-1618832), I had a problem accessing one particular domain after doing everything I could find to fix it. Setting DNS to Increased Protection fixed it. It's partly just curiosity but also concern that I'm asking if there is an issue that should be addressed.

The basic scenario: could not access one particular domain only in FF on one computer. No problems with FF on other devices and no problem with other browsers on the computer in question. Configuring DNS settings to Increased Protection is the only thing that allowed me to access that site (which happens to be the org I work for). So the setting is only necessary on this device and only for that domain.

What's the explanation or solution for ensuring I don't have other DNS issues, or something else, that will be a problem later?

I used to be able to use the backspace key to go back one URL in a given window. Now, even though I have gone to about:config and changed browser.backspace_action = 0 to 'true', this no longer works, at least not with my new Windows 11 computer. I tried closing and re-opening Mozilla with the new preference, and again with closing, restarting the computer, and then re-opening Mozilla. Please help if you can. Thank you so much.

On both my old laptop and a new one (so a new installation of Firefox), I'm unable to load Frontier Airlines' website (www.flyfrontier.com) and get a time-out message:

The connection has timed out

The server at flyfrontier.com is taking too long to respond.

   The site could be temporarily unavailable or too busy. Try again in a few moments.
   If you are unable to load any pages, check your computer’s network connection.
   If your computer or network is protected by a firewall or proxy, make sure that Firefox is permitted to access the web.

This happens even with all of my extensions disabled, with enhanced tracking protection turned off for that site and with HTTPS-only mode and DNS over HTTPS disabled. It also happens when using Firefox in safe mode. Safari loads the same website very quickly and with no problems. Does anyone know what might be going wrong? Thanks.

I have a Logitech mouse. I've used it with both Brave and Chrome problem without problems highlighting text. But the highlight function doesn't work properly with the mouse in FF.

I can double click and highlight a paragraph. I can highlight a single word with no problem. But when I try to highlight a series of words or a full sentence, I can't. Either it highlights but when I try to Copy the highlight disappears. Or when I drag the mouse to highlight it won't highlight at all.

Since the issue only occurs in Firefox and not other browsers, there has to be something in Firefox that's causing this; or some conflict causing highlighting not to work.

I'd be grateful for any ideas how to fix this. It's driving me crazy.

I tried to watch a youtube livestream today and it failed to play. Non-live videos on youtube are playing, even the same videos watched as VODs after the stream ends, but the livestreams are providing "Your browser can't play this video" errors.

Simultaneously, I'm noticing that some videos on Reddit (such as embedded tiktok videos) are stuck with a circling ring and won't play. At least some of the same videos will play on Tiktok (when I can find them).

ALSO, when I try to watch videos on my Nebula subscription, I'm getting a "This video could not be loaded: 4" error code. ANY video on Nebula.

What the heck gives?!

There is one domain that I get a "server not found" error for even after doing many things to fix it including everything here, https://support.mozilla.org/en-US/kb/firefox-cant-load-websites-other-browsers-can#firefox:win10:fx119, checking blocked URLs in the registry, running malware checks, safe mode, reinstalling FF after removing all FF folders from my system.

Before I did a completely clean reinstall, disabling the Open H264 codec (see attached screenshot) would allow me to access the site. But thinking it was needed, I did the clean reinstall. Now disabling it does not allow access to the site.

So far, I have not found any other websites with this problem. It's a .edu domain which happens to be the one I work for! What else can I do?

Hi, so here's the issue I have: Lets say you have 20 tabs open where the "tab scroller" becomes active and tab#17 has a video, if you enter & exit fullscreen on that tab then tabs #18-20 will slide to the right and go out of sight. This is quite annoying as I'd prefer all tabs on the right to be visible until I manually scroll to the left.

I tried googling for about:config or userChrome.css solutions but couldn't find anything, does anyone have any ideas on how to change this? Thanks.

Firefox version: 119.0 (64-bit) OS: Windows 10 Home 64-bit

Hello,

Whenever I open a local HTML file, Firefox tab will crash. This happens if the HTML file size is big (>4MB), smaller file doesn't crash.

I've tried opening the file on Chrome, it doesn't crash and open just fine. So it seems like this is a bug with Firefox.

I've uploaded the HTML file if anyone wants to test: https://www.mediafire.com/file/ipmu7ugrd2vvelr/LICENSES.chromium.html.zip/file

Thanks

When I go into fullscreen, by any means (F11 or dedicated button next to zoom settings), only the firefox toolbar disappears. The window taskbar stays there. Issue is not present on other installed browsers.

I tried: - Troubleshoot mode - Tinkering with windows accessibility settings for Firefox - On troubleshoot mode, Individually flipping these configs (+ refresh): - - browser.fullscreen.autohide - - browser.link.open_newwindow.disabled_in_fullscreen - - browser.link.open_newwindow.disabled_in_fullscreen - - widget.windows.fullscreen_remind_taskbar

I've searched for answers. I tried the About:config and changing some settings to false and others to true as suggested (e.g. browser.search.context.loadInBackground), etc., and of course I have the option chosen under settings.

This is a new computer. My old computer would switch to the new tab when I right click it, but this new one won't.

Any latest fixes?

Hi,

After updating Firefox to 116.0.1 my tabs keep randomly crashing. I get some crash reports *occasionally* - meaning not all crashes produce a crash report - but I'm not sure what to do with them, they seem inconclusive. The last report (not for the last crash, though, which didn't produce any report) is bp-3334b934-58b5-4226-887a-235300231117

Hello,

As I said: fresh install of FF 119, only Privacy Badger and uBlock Origin icons are showing on the taskbar. I tried TyDraniu tip "Click the jigsaw puzzle icon, then right-click on an extension, then select Pin to toolbar" but with the right click there is no such option as "Pin to toolbar".

What's going on?

I don't know if it is because i closed firefox task end, or if it is a bug from update to v119 (when i reopened firefox, there was the updated tab). But now when i fly my pointer on "recently closed tab", instead of only having the 15 last closed tab of my current firefox windows, i have also the 15 of each opened firefox windows. means if i have 2 page it show 30 tabs, etc. the first 15 being the tab of the current windows (ex: FF windows 1) and the 15 next for the other opened one (FF windows 2), when i check "recently closed tab" on the other windows it is reversed (the 15 first tab are the windows 2 closed ones, and the 15 next from the windows 1). It is me, or a global bug (or new feature). If the second, how to return to the former option (means having only the tab closed from the current windows showing)

An answer from legit source (longtime moderator or developer) is welcome. I'm sorry if this has been asked before. I couldn't find it and I'd like to make my point.

I didn't like the design of Firefox when they first started this design with so much space wasted for tabs and toolbar. Every time I open Firefox it feels odd with gigantic empty spaces if I come from Chrome/Vivaldi which are thoughtfully compact.

I have 14" laptop and Firefox makes the UX very less intuitive.

As of now, I'm using the workaround for compact mode that was posted in this forum numerous times. It says (not supported) beside compact mode which makes me feel like that this feature is going to be removed completely in the future. That's the tipping point where I will stop using Firefox completely.

So, coming to the question - wait - Subject is the question...
