Firefox Support Forum

I have a website that I host. It is behind a proxy. It is a resolvable FQDN with DNS hosted by a major provider. The issue is when I browse to it via Firefox 124 it eventually errors out with connection reset, however if I open a private window it goes right there. I have tested other browsers and it works fine with them (Chrome, Safari, Vivaldi). I thought maybe it was plugins so I tried shutting off plugins one by one restarting after each one and that did not help. I tried in safe mode and could not get there. So I backed up my bookmarks and wiped out the directory and all for Firefox and tried on a fresh directory and that did not work except in private window mode.

I'm a cybersecurity professional and I'm researching about Same Origin Policy, Cross Origin Resource Sharing and how firefox deal with those things. I've find out that versions before 102.1.0esr, cross-origin script GET requests used to attach cookies (Image 1), but in newer versions, it's not happening (Image 2). I checked the release notes but didn't find nothing about this change.

I would like to learn more about what changed and how Firefox is dealing with cookies, SOP and CORS.

Thanks!

I use Duck duck go as my default search engine. I've noticed that after the last couple of updates, the default has changed to Google. This has not happened before. There must be a bug somewhere that is causing this to happen in the new version of Firefox.

I'm having problems with Firefox using 75% of processor capacity. In "top" I see many instances of "Isolated Web Co".

At the moment of this screen shot the processor is not overwhelmed, however, it will sometime jump up to 75% and the system will seem to freeze.

What is the "Isolated Web Co"? I'm thinking a virus.

Thank you.

Im trying to halt fingerprint tracking, whoever designed Firefox's privacy.resistFingerprinting rule makes fingerprinting even more prevalent.

With privacy.resistFingerprinting set to FALSE, my resolution is reported : 1920x1080x24, set to TRUE its 1920x968x24

1 in 6 browsers has resolution 1920x1080x24 1 in 6000 browsers has resolution 1920x968x24

Who in Firefox decided this config rule? and what is the logic behind it? Looks like intentional sabotage to make peoples browsers more trackable.

Whilst leaving resistFingerprinting set to TRUE, How can I force my resolution to the more generic 1920x1080x24?

Is there another setting in about:config I can change? if there isnt, where can I request this feature? Id rather not resort to an extention for something so small like this.

When I open a new tab in FF, a row of 8 boxes appears below the search bar where I can add shortcuts. I currently only use 5 of them, meaning there are 3 empty boxes left over. I don't want to have them show history, or recommended websites, or anything of the sort that might distract me; the shortcuts should only be those I actually intend to use, of which there are only 5. To my knowledge, the only easy way to add/remove shortcuts is to adjust the number of visible rows, but this only allows modifications based on multiples of the original 8. Like in Chrome, can I actually remove any excess shortcut boxes I don't want to use? I feel this is a very basic customization I'm sure Firefox should be able to accommodate.

I've included a screenshot of my FF new tab, where the three empty shortcut boxes I'm referring to can be seen. Thank you in advance for any assistance!

I'm using 121.0 for Manjaro

Today, I had a problem trying to re-load a website I had saved just the other day. I have a bunch of such websites for a technical project I am working on.

I tried loading the other saved web-sites. All had been saved as a complete file and by this browser. I have no other browser installed.

The problem was that the saved web-page kept re-loading. No forum-discussion could be found so the trouble-shooting option was entered into.

I opened Firefox in safe-mode (via the command-line call). Running a suggestion; clearing cache didn't resolve the problem (in safe-mode the saved web-page still kept re-loading with a rapid cycle)

The next "suggestion" I tried was refresh Firefox. Firefox advised that none of my saved data and settings would be lost. Well, my entire profile is gone!!! Thankfully synchronizing worked such that I could recover passwords, history etc. What are NOT recovered are the settings for websites, probably other infos too.

I have two login-accounts on my system and I have a shared, common profile for both. This was using a public folder with access rights only for those two users.

I have been using that profile architecture for months. This is now gone!! Those folders do not exist anymore. In its place are entirely new folders, their formats completely unfamiliar to me. I am recalling my latest backup but will it be of any use???

Many thanks, indeed.

Why is mousewheel.with_control.action = 5 not the default in 2024 ? or at least an accessibility features ? I have multiple over the years had to help my older parents with `broken` website due to the actual default increasing the font size instead of behaving as a pinch and zoom

The fcitx input method works everywhere on my computer except Firefox. I've added the following to my etc/environment file, which is the main suggestion I found online: GTK_IM_MODULE=fcitx QT_IM_MODULE=fcitx XMODIFIERS=@im=fcitx But it still doesn't work. My operating system is KDE neon 5.27.

Bangirot says technical problems when I want to see my received bankgiro payments. Win10 with Firefox, I can't see payments on that machine for a month soon. I have reinstalled firefox now. Still same result. With Android phone and firefox it works, but without printer. With another browser on Win10 it works, but not with firefox. Swedbank internetbank or bankgirocentralen can't help me. They have not heard of such problems.

Internetbank works, but with their connection to bankgirot it says, tehnical problems. If I login to bankgirot directly, it says tehnical problems.

So far its only the combination with this machine and firefox that gives this result. I haven't tried with another machine yet.

I have used firefox very long time without any problems.

I am running Firefox 122.0 on Ubuntu 22.04. When I have a decent number of tabs open, firefox will often randomly decide to lock up completely. GUI is almost entirely unresponsive. I can right click the menu bar area and get the Menu Bar/Bookmark Options/etc. context menu, but it's also screwed up (2 options that are normally there are completely missing). This has occurred for a year or so. Originally, I used the snap version but recently backed up and switched to installing from .deb. Still the same issue. I saw recommendations for turning off hardware acceleration, and that didn't prevent the problem. Running `top`, I see that I always have plenty of memory (at least 10G free) free and worst case 1 thread is being run 100% but the others are hardly being utilized. No crash reports are generated (I will pkill firefox to stop it). Addons and extensions are all disabled.

I recently realized that hitting the windows key with firefox frozen will allow the web page to show again, but it's back to frozen. I keep hitting the windows key, and it will unfreeze just momentarily to show me the current webpage that is up. I can also Ctrl+N and open a new window, and the new window works perfectly fine independent of the completely frozen first window.

can anyone of you test chat open ai com with linux 32 bits?

for more than 5-7 months its been unusable. it completely freeze. I recently reported this to open ai devs and they tried to do something. Now page responds is in 20-60 seconds range.

means, I open website, i wait 20-60 seconds to load. I ask chat gpt something, i wait 20-60 to actually type my messsage (for my message to be printed after I hit enter). then i refresh page (because nothing moves), wait 20-60 secs to load page and I see the reply.

and yes, each time I was always trying to do with latest version of browser. and I also tried it on a new browser without any extension.

I have a video, I can only share it private with firefox devs if helps.

the reason I didn't reported this last year, was because I got extremely disappointed and unhappy.

it initially started by showing that button-bar at the top, telling that page load slow and to [stop]. by the next month it became worst than 2000's dialup internet, so I stopped using it

Hi, I am using Linux Zorin and have updated to a later OS but cannot reinstall my stored files because, "/home/garry/.mozilla/firefox/0czvkt76.default-release/lock". Which has confused me, I have used a Deja Dup backup which uses Duplicity files as per the Zorin programme. Duplicate files are stored in a WD ext hard drive. What can I do to recover my files pls? Appreciate! Cheers, Garry

The Amazon.co.uk search plugin was working but now its not and when i try to click "add search engine" a box pops up with

Firefox could not download the search plugin from: https://d2lo25i6d3q8zm.cloudfront.net/browser-plugins/AmazonSearchSuggestionsOSD.Firefox.xml

another post suggested checking the about:config browser.search.region mine says "GB" which would be correct for .co.uk

All other search plugins work fine. Any suggestions?

I am using a two finger scrolling on a touchpad to scroll vertically in Firefox. How can i change the scrolling in Firefox to be like vscode or konsole. I want the scrolling to not have a delay and be instant.

I want extensions to have white/black-lists, so they're only allowed or blocked on certain pages e.g facebook container ruins instagram experience... and I can't block it on *instagram.com* Such feature would significantly enhance UX on firefox

Thanks, Rob.
