Hello,

Please add this feature in Firefox and Firefox developer edition

I am wondering when i open firefox developer edition. All the tabs will be open during stating firefox developer edition.For better understanding this feature is already in google chrome.Please search this in google

Open a specific page or set of pages

So, certain web pages apparently have text in white font color while also using a white background. I'd blame it on the team behind the page, but it seems that it works well on Chrome, so I'd like to know how to fix it.

Examples: 1: http://ipm.ucanr.edu/QT/parasitesinsectcard.html 2: https://www.userchrome.org/how-create-userchrome-css.html

Add-Ons: ThanksToYou tabs Speedtweaks (none active at moment of taking screenshots, though) OneTab.

I'd add images, but they take way too long to upload

Hello,

I am a Web Developer, fixing a website for my client. After the page is cached in Mozilla Firefox the layout breaks, when I clean the cache everything is back to normal. This issue is only present in Mozilla Firefox, I don't have that issue with Google Chrome.

Website URL: https://www.impeccablex.com/ Please see the screenshots attached, you can see the layout before and after.

I have tried almost everything that I could think of, don't know what to try next. Any suggestions?

Thank you in advance! Best Regards, Mario C.

I'd swear that I used to be able to click on an animation/video/gif to stop at looping, but I cannot stop this one by doing that:

It must've been one of those custom settings I had before I got the new computer and ran a clean install of firefox.

I have set media seamless looping to off in about:config, but I can't see what other preferences would relate to this.

Mac OS 12.0 Monterey, FF 94.0 beta

Hello,

Whenever I use Firefox, I end up seeing popups (necessary for school) and would like to show them as tabs so I can merge them into other windows. I have tried the solutions given in: https://support.mozilla.org/en-US/questions/1080255 and nothing seemed to work. Is there another way to make sure that popup windows cannot hide the toolbar and show tabs?

Dark Mode used to work beautifully in Firefox. Today it stopped working. I can choose Dark Mode in the settings page, and the settings page itself then uses Dark Mode. But Dark Mode does not work in any of the other pages, only the settings page. I think it must be a flaw in an update that was installed automatically today. (September 7, 2021)

Is there a way to uninstall this update and go back to the previous version. Dark Mode used to work beautifully and Firefox was my favorite browser. Can someone help? Thanks.

I downloaded firefox developer edition from: https://www.mozilla.org/en-US/firefox/developer/ But almost every 5-6 days it shows a prompt saying firefox have an update, download it from website we will help you install it. It's inefficient and time consuming to manually download and setup firefox after every update.

Last few days any Firefox 102.0.1.8221 launch causes my Windows 7 64bit to reboot, usually when I try to mouse click anything in Firefox after it's fired up and restored open tabs, however even if I don't mouse click anything Firefox will force a reboot within a minute or so.

This Firefox Win 7 reboot behaviour only started after the last Firefox update, though I would point out that around update version 100.nn I started getting failed update notifications from within Firefox which necessitated a manual newer version Firefox download and install.

Running Windows 7 in safe mode with networking on allows Firefox to function without crashing, albeit slowly and with no MSE protection available etc.

Only one crash report dated 16/07/2022 with following content: Crash ID: bp-d8383165-9c77-45e4-9929-a3ce12160527

Please note I'm sending this report via Firefox on my iMac coz that still works...

Why can a stupid failing script on a web-page, or even intentionally so programmed script disable the copy (and sometimes paste) functionality?

How can this be disabled/fixed?

One highlights a text (any text) on some web sites, Edit menu allows Copy, context menu allows Copy, one hits Copy, nothing happens. It's not even a page where someone wanted to "copy protect" some information.

Copy and Paste should work just as advertised since those were invented, how hard can it be to get that right? Even stupid Notepad never fails at it. And no, I don't care what the idiot who programmed a page though would be/should be best for me, I want Copy to be copy, Paste to be paste. This used to work in "original" Firefoxes even when page developers wanted to make it not work.

And yes, while on a given page Copy fails miserably, at the same time in other pages it works.

Hello, Since my last update, Firefox 93, my bookmarks present a huge line spacing between them, line spacing that I would like to control to see more bookmarks at a time. Do you know how to proceed ? Thank you very much.

When Firefox asks if I want to download an update and I agree, soon after that but not right away it stops working - on every new page it says "We need to restart to finish updating" <- This last bit is VERY annoying. Is there a way to keep FF working in such situation? I usually have 3 FF profiles running, about 10-20 tabs each and when it suddenly does this - I can restart them all but when it is suitable for me.

The only solution I can see so far is disabling updates via group policies (which is not well documented, where do i put this policies.json on Fedora? need to google that).

Any other ways to keep updates and FF running until I decide when to restart? Thanks.

Hi, in an update recently my address bar has changed to show my search history or similar named things instead of just the website itself, how can I change this back

Also the search bar on the right increased in size or no reason, how can i fix this.

Still trying to figure out what is wrong after refresh of Firefox.

I cannot get my handful of preferred websites to remain logged in when closing and reopening Firefox.

I have FF set to clear cookies and data on closing, but this handful of sites are listed as exceptions.

After reopen FF, the relevant cookies are not sticking. This used to work better.

I redownloaded FF and no improvement.

I'm thinking conflicting settings or....?

FF beta for Mac OS, 93.0b3.

Hello! I am in a work environment and I am trying to determine if there is something in our security systems that is preventing Firefox from running properly. Once Firefox is installed, it works the rest of the day with no issue but almost daily the morning after, it will start to open then instantly crash. When I check the crash logs, it shows in most of them: Modules - Filename: umppc14210.dll Version: 6.28.14210.0 Debug Identifier: B9143DE260194C88AB48EFD6782C9EAF1 Debug File Name: umppc.pdb Signed By: Microsoft Windows Hardware Compatibility Publisher

Some are this instead: Filename: umppc14105.dll Version: 6.27.14105.0 Debug Identifier: CE458B39D37A4C65A60024BBACED6EB31 Debug File Name: umppc.pdb Signed By: Microsoft Windows Hardware Compatibility Publisher

When using the dark theme from Firefox, Google searching seems to break completely as well as some pages will not load which may be related to this.

I have already tried uninstalling Firefox, deleting all of the folders, then reinstalling with a freshly downloaded installer (Even tried the beta one) with same results. It seems potentially MAYBE related to how long ago I closed Firefox before I shut down (Like Firefox is trying to save something to a secure location and times out, then it will work but if it hasn't timed out, then it crashes... or this is my guess)

The Signature seems to change randomly for the crash between crashes.

I really am tired of constantly reinstalling Firefox but I do not want to use Chrome or Edge unless websites require it.

Is there any way I can completely disable horizontal scrolling? I'm using a laptop with a trackpoint (lenovo x230, Windows 10) and it's not terribly accurate, which means scrolling whilst a youtube video is going often makes it track backwards or forwards, and another website I use uses a horizontal click to send me to the next page, which sucks. I would prefer to just be able to disable it entirely. Thanks!

I swear to god I used to have it disabled, just need to work out how again.

I browse web, I see an image to save. prior to today (03-09-2022) I click save as and it saved file to my downloads folder. but today, I click save as and instantly the list of files I saved pops up on right side. below the list of files it shows "show all downloads"

this window is easily accessible by left clicking clicking the download icon. i do not want this box popping up on each file/image saved. or rather, why is it doing it suddenly?

running 2 addons: TinEye - reverse image search Video DownLoadHelper

both of these I have zero issues with and have been running them both circa firefox 45? or older
