Hi,

Firefox version: 139.0.4 (64-bit) OS: Windows 11

I have been having issues where Firefox tab will just crash out for no reason it appears and it happens at random times and once the tab start to crash, and I restore it, it will crash again and again. The only way tog et out of the loop is to restart Firefox.

I have tried: Refreshing/Reset, Clearing Cache and History removing all themes, disabling extensions, disabling my anti virus. Turning off hardware acceleration didn't make any different.

I currently have 2 extensions enabled: uBlock Origin 1.64.0 and Bitwarden Password Manager 2025.5.0

In the about:Crashes I have reported them all and they seem to have the same type of reasons in the Raw data/Minidump which are: EXCEPTION_ACCESS_VIOLATION_WRITE EXCEPTION_ACCESS_VIOLATION_READ

Any help as to what to try next?

Hi, for some reason, I am severely restricted in size when uploading files to Facebook, with a maximum .jpg size of under 50k. I do not have this restriction in Microsoft edge, or on my phone, only on my laptop. I do not have an ad blocker installed that I am aware of. Appreciate any help. Cheers, Merv.

I am no longer able to send an article or something downloaded from the internet, via the email option offered, because I just get my own email sign-in box in the past and I want to be able to use this option again. Please tell me if there is a setting that's been changed. Thanks.

I saw my same issue described in an archived thread "Several users have reported connection issues with Google sites including YouTube. This has been linked to the "zero round trip resumption" feature. That is intended to speed up website connections, but there seems to be some kind of compatibility issue. Currently, there is only a hidden way to disable this and see whether it helps".

I tried the method given (going to about:config and turning security.tls.enable_0rtt_data to false) but it did not work.

I tried uninstalling and reinstalling, but I accidentally dragged the Firefox in the installer directly onto my dock (on Mac) and that Firefox was working perfectly fine. But I noticed there was "Firefox" drive running on my system. To fix it, I realized I had to drag the Firefox in the installer into my applications folder and run that Firefox. So I did so, and ejected the Firefox drive.

Using the new Firefox that was actually installed in my Applications, I am now stuck with the same problem of Google sites not being accessible.

Firefox has just introduced wallpapers for browser home page. I cannot get it to work. It's either cropped too small or pixilated, is there a setting I need to adjust, or a particular image format? So that it looks ok.

I want to save a shortcut on my desktop that will access a particular site in Firefox using private browsing. It appears (?) years ago you could do that by adding -private to the end of the target. That appears to no longer work.

Suggestions?

To replicate this issue, an image from my device is uploaded to a website that requires an image file input; the resulting image displayed on the website becomes corrupted and unreadable. The theory forming currently is the website is having issues retrieving or reading the input images; however, this bug seems to be consistent with several other websites, indicating Firefox is not able to read the images correctly and thus could result in fragmentation. - The image posted is a .png file of a screenshot of an attempt to post a picture to social media, based on the functionality of this bug, I am predicting this image will be fragmented and will only show blue and black lines. The image being posted online is also in a .png file format.

I use Firefox on many computers in many locations and they all use the account sync feature. However, at one location, a school, there's a filtering system in place called Securly. To get through the school filters, you have to download a certificate and install it. I do that, and web browsing works fine. But, syncing does not work. It's as if the syncing feature doesn't use the installed certificate. So, to sync, I have to use my phone hot-spot from time-to-time. It's a big pain, however, when I've set or changed a password at the school and expect it to be available in all my other computers but I've forgotten to do the manual sync before I left. Is there a way to get the sync process to use the installed certificate?

Thanks!

When assigning a URL to the mediaplayer object it started appending the current path to the URL. Did not do that in prior version. You can see it automatically puts the current browsing URL and then the URL that is assigned. So the file will not load.

Hi,

I get a pop-up saying ww25.cloudflare-ipfs.io is a phishing site should I just block it or add it to the exceptions list. Also is it required for firefox to work properly

I am sitting in hospital with a weird problem. The connection is open and thus not secure. I have successfully connected my 2 android devices, however my Windows Asus laptop is being barred by firefox. I only run firefox. It is a dead end because firefox refuses to allow me to access the net at all. So now I have to get my wife to go and download chrome and see whether that will work. Why can I not override as u understand the risks I also use Norton 360 with its VPN.

Why do I get "Could not establish connection. Receiving end does not exist" when I use Roboform's option? I think this started after a Firefox update. My whole homepage changed with the update.

Hello all:

Just downloaded version 140 and ran into an immediate "visual/appearance" problem with regard to the background color(s) of the sidebar bookmarks view. Many themes now have totally dark sidebar colors and not readable (see screenshot image upload with this posting). I always have my bookmarks (almost 1200 of them) displayed in my sidebar, and this is the first time an issue like this has arisen with a Firefox update.

To remedy this scenario, I must use very light colored themes that have a white background when you bring up the sidebar bookmarks. If not, everything is totally dark and unreadable.

Any ideas or help on this one?
