I am trying to access websites that use three.js. When I initially start, the website runs too slowly to be usable, but if I tab out for some time and then tab back in, the website runs at normal speed for a bit before slowing down again. I cannot find any solutions to this problem nor anyone else who had the same problem as me.

OS: Windows 11 Home 23H2 (22635.3720) Firefox Version: 126.0.1 GPU: GIGABYTE NVIDIA RTX 4060 Ti 8GB GPU Drivers: Game Ready 555.99

Today for the first time after the latest update 127.0 (64-bit), my many firefox pages and tabs crashed and closed and a pop up to send crash report.

So I have fired up firefox again to find only a single page opens up, I have lost probably 16+ pages with multiple tabs on each, been like that for months, I have 32GB memory so there is normally no issues or slowness. However after the crash, even though only a single firefox page is open, windows task manager shows Firefox (20) and if I expand the task, I can see each firefox is taking lots of memory.

So it looks like the old session pages/tabs are still there somewhere but not accessible, I would like to get them back if possible. I went through reseting it to default, disabling the add ons etc but nothing has worked.

Is it possible to install Firefox (or at least the profiles) onto an external SSD (i.e., not the C: drive)? If so, how?

Note: this is not about migration/backup/recovery of profiles. Nor is it about where files are downloaded by default.

Windows 11 is consuming nearly all of the C: drive. I badly need to get Firefox (and later Thunderbird) onto my E: drive. I further note that the installer gives no options whatsoever as to the destination drive.

Most of the help I've found on the web is clearly outdated.

Thanks. jt

I want to create a link in the bookmarks toolbar to easy check and update firefox In chrome I can do that with creating a bookmark to: chrome://settings/help In edge I can do that with creating a bookmark to: edge://settings/help I have search for, but cannot find the equivalent in firefox

ALT-SHIFT-LEFT has been 'select word backwards' for years, at least on macs. And so it was on FF too. Now they suddenly decided to re-map it to 'select left tab'. There was already a key for that - CMD-ALT-LEFT. Which also works for the right, whereas ALT-SHIFT-RIGHT does nothin

Good Morning. I have been using Firefox for 20+ years. Last night it did an update overnight, and this morning I am getting "The Page Isn't Redirecting Properly" error message on my business CRM site. This appears to be the only site having an issue. I have never had this error previously.

I tried all suggestions already including clearing cache/cookies, checking settings, delete history, troubleshoot mode and nothing. The site opens fine on Chrome and MS Edge.

Any additional help is appreciated, this is very frustrating.

Thank you.

I've posted before but no answer as to why Firefox labels Paypal as an unsafe site. I don't know where to change settings to allow it without the warning. I've just ignored the warning and continued but it is annoying.

In previous versions I was able to open around 15-20 tabs before X button disappeared from them and I was no longer able to close them without activating them first.

Now this happens much earlier - only 10 tabs is enough on my 1080p 100% scaling desktop and 9 tabs on my 1080p 125% notebook.

X button is present if you have 10 tabs or less, but disappears with 11 tabs, when there is still plenty of space on tabs to click on X!

I compared it to brave and in brave you can still have 22 tabs opened before X button disappears!

Anyone has any method to force presence of x button? This is really annoying as I often have much tabs open and close only 2-3 of them. Now I have to open each one again to be able to close it.

Websites say that my Javascript is disabled, but I already checked on the about:config website and the javascript.enabled is set to true. What do I do so these websites accept that my Javascript is enabled?

On my computer Firefox ask for the master password every time at startup. On other computers in my family, Firefox only ask for the Master Password when accessing a site with a password. I tried : - to disable than reenable Master Password - start in SafeMode without success. How can I solve my issue ? Thanks in advance for your help

since the last update, the shortcut keys to highlight a word at a time left OR right are both highlighting the next word AND also jumping to the last tab. AGAIN! I noticed this was identified as a problem back around 2019 in a search. I now cannot move fluidly within text, nor highlight a word at a time quickly. Either it's whole line or simply a letter at a time... which results in a pretty incompetent, crippling experience. PLEASE FIX!!

Hi! I'm using Firefox 126.0 on Fedora 39.

Pages from Amazon.co.uk load very slowly, incompletely, or not at all. All other Web sites are fine.

I had a couple of certificate-related errors saying that the identity of the site couldn't be verified, but I can't reproduce the problem, so I can't quote the exact wording, I'm afraid.

The same Amazon pages load properly in Chrome on the same machine, and they load properly in Firefox in a VM on the same machine. That tells me network connectivity must be fine.

I've tried disabling all extensions, reverting to the default theme, running in Troubleshoot Mode, clearing cookies and site data, clearing the startup cache, disabling hardware acceleration, and creating a new profile. The new profile helps slightly, in that it loads more of the page before getting stuck. Nothing else helps at all.

I'd prefer not to refresh Firefox if I can avoid it, because I don't want to lose all my plugins and settings. This installation is five years old. Besides, a new profile didn't fix the problem.

What's the next thing to try? I'd really appreciate any ideas.

Hey there,

during work I often open two windows of Firefox to have more information visible on my two monitors. Unfortunately I sometimes forget that I have a second window open, so I close only my "main" window and loose all tabs.

Is there a way to force Firefox to ask to close a window and loosing multiple tabs for every window open?

Right now this only happens for the last open window.

PS: I just found out about the keyboard shortcut of restoring a window (CTRL+SHIFT+N) recently. I would prefer a setting in my case.

Thanks in advance Fred

Youtube audio is extremely slow, I reckon at 10%, but the video is fine and can be sped up or down. The problem persists even in troubleshooting mode, after cache clearing, hardware acceleration turned off, enabled DRM and widevine, driver updates, in private mode or not, logged in or not, firefox restarts, computer restarts.

But Youtube plays fine in Chrome and Edge.

I dont think I didnt anything drastically different, or updated win10 or firefox, or messed with anything. It was working fine a day ago.

Is there any way to reset something?

Hey guys,

I saw in the following post that I can modify the zoom values of Firefox to custom values of my choosing (e.g. 75%, 85%):

https://support.mozilla.org/en-US/questions/1201469

I followed the instructions but it did not work for me. Yes, I did save the changes I made, and I completely closed & reopened Firefox, but the changes I made have not been applied for some reason. Please see the attached image.

I would have ask the question in the aforementioned thread but it's been archived so I had to open a new one. Does anyone know why Firefox does not seem to recognize my custom values (.75, .85)? Thanks!

Hi,

more Details concerning the problem you can see here ! It should be great if you could help us with some diagnostics, for example why the problem only appears with FF on Linux, not with FF on WIN.

STR:

1. Launch Linux FF
2. Visit this page "Potential issue with plugin PITM" (Preview here
3. Because you will need an Account for visiting account please follow "Konto eröffnen" (Create Account) instructions).
4. After my approval for the account please visit again "Potential issue with plugin PITM"
5. Click "1.png" Below heading "Attachments", that should work without problems.
6. Close image view
7. Move Mouse pointer to image below heading "My test with a screenshot" – should become magnifier
8. Now Click that image

  » Expected (and so it does with WIN): Big image opens in new TAB
  » Actual:  New TAB opens, but without image view.

What are your results? FF Linux Problem or something else?

Hi Guys,

This is a recent hiccup and only seems to affect Firefox 126.0.1 & 127.0 (I'm running Win64 EME-free):

I have a HTML file which displays images from various weather-cam websites, using the HTML "img src=" tag.

On previous versions of Firefox all was fine, however since 126.0.1 one image in particular will not display - it simply shows a broken image place-holder. Using MS Edge and Chrome, it displays correctly.

This is the image in question:

http://119.17.143.158:8777/Streaming/channels/102/picture/?auth=U1BDRzo1NG5keXAwMW50IQ==

I suspect it's something to do with the "auth=" 'key'?

Thanks in advance for any suggestions/assistance.

Mike.
