Firefox Support Forum

Hey there, awesomes! I'd like to change my Firefox pdf viewer's background color (both sides of the pdf) to dark, currently it shows light gray (see `background_bg.png`). And here is effect I want it to look like (see screenshot from Chrome `wished_bg.png`). Thanks in advance (:

PS: I don't want to change my theme to dark. It seems I have to change my css, but I dunno which & how.

Hello,

I am using Firefox version 92. The screenshot function is not working, both if I right click and request a screenshot from the slideout menu, and if I request a screenshot from the shortcuts/overflow menu (scissors icon). I have attached a screenshot (taken with ‘prntscr” through windows) png of the result that takes place on my screen. The screen will freeze with this image of a large X until I do a refresh of the page. Cntl-Shift-S also does not work. I have tried clearing the cache, running FF in safe mode, refreshing FF, reinstalling FF, and I have ensured that the extensions.screenshots.disabled setting in about:config is set to ‘false’ (also toggled it to ‘true’ and back to ‘false’). I have attached a screenshot of all the settings in about:config that pertain to screenshots.

Thank you for your help.

The possibility of moving icons of those extensions will be a huge improvement.

Please send through to the right department. If those functions still aren't available jet.

Thanks a lot, See the attachment for the example image.

Yesterday when I installed the 96.0 update it has forced my background color into a dark grey and ignores the background color setting. I would like to know if there is a setting, add on or update that can return this to normal. The theme I am using has not been updated in 2 years so I am fairly sure the update has caused this.

I 'refreshed' firefox as suggested. The guidance suggested that all my logins and passwords would be preserved but when I check the Logins and Passwords all have been cleared. I am now faced with the arduous task of resetting many many login credential. Poor advice from Mozilla.

All things I try to download on Firefox are extremely slow compared to other apps like Steam, torrents and other apps. I get 90mb/s on the download speed checks, but when I try to download something on Firefox, it downloads at like, 120 KB/s.

My firefox installed a new update, 89, and now my tabs are missing, except that the active tab is floating down at the center bottom of the screen. i can still navigate with keyboard shortcuts, but i don't know how many i have open, what they are, and personally DO NOT like navigating with shortcuts if i don't have to.

why is it necessary to keep messing with tabs? weren't they just fine below the address bar back in the day? How is ruining the user experience worth whatever was even trying to be done here?

image is how my firefox looks right now

I need an email address or a phone number to contact support. Forms do not have answers for my problem. And the contact and the support pages have no information on how to contact Mozilla which is extremely messed up. Does anyone have this info?

Please help me get rid of the stupid and ugly Tab bar space on newest Firefox. I hate Tabs and now there is a big space above the address bar for Tabs. I have looked everywhere for a way to turn it off like it has been since Tabs came out. I only want new windows if I want a new window.

If I can't turn that huge space gap off is there any way to go back to what I had before the last update without messing everything up? Why did someone decide to make the browser window smaller and waste that space by making the browser bigger....

Sorry if I sound cranky but, I started using Netscape Navigator 1.0 and every version since and this is the worse thing that has ever been done to a browser... Thank you for any help you can give me!

I "upgraded to V90. since then, the URL box is highlighted red/grey stripes. The robot head icon is now in the URL box and it says "Browser is under remote control (reason Dev Tools). I've gone in about:config and set all variables to False, yet they reset themselves to true every time. How do I disable the DevTools. Thanks

Widevine will revoke Widevine Content Decryption Module which is earlier than ver 4.10.2209.0. https://www.widevine.com/news

Google has already released new version of CDM. However, the version on Firefox 88.0b7 is still 4.10.1582.2. You can check on the following menu: [Add-ons and Themes]>[Plugin]>[Widevine Content Decryption Module]

My questions are: 1. When is new Widevine CDM coming to Firefox? 1. Can Add-on Manger provide this update to older Firefox?

The page Give feedback landing page says: ‘Please check back soon’. What does ‘soon’ exactly mean?

Attached is a sample of how web pages display. These can either initially display this way or, as in this example, the page opened correctly, I stepped away for a few minutes and when I viewed the page again it looked like the example. I can have a page open and it is displaying correctly, then open a new tab and go to a different site and the text will look like the example.

I have cleared the cache, dumped all the cookies. Restarting the browser (I do this many times a day) will fix the current page but eventually another page will display like this.

I running version 84.0.2 64bit on a Mac Pro Mojave. I don't have this problem with other browsers like Chrome or Safari. I never see it on my Windows 10 system.

After Firefox updated my bookmarks are all screwed up. I can see very few and the icon on the top right is not there any longer. I can see them backed up on a HTML file in my desktop but I can't import them back. What's going on?

I'm currently in my vacation home and I don't have home internet here. I'm connecting through my mobile phone using limited mobile data. and I selected not to download updates because it keeps updating itself like twice in a week and every MB counts in limited data plans especially if it's just 4 GB total for each month.

But now every time I open the firefox it showing download latest update popup like an annoying virus on the top right corner where 3 horizontal lines are located.

I checked the internet and previously this was an option in it's settings. Then this option removed and only hidden behind the about:config . and now it's completely removed from about:config either.

The only reason I switched from chrome to firefox was because google became an absolute dictator lately and all it's changes was to limit down my accessibility. I switched to firefox becuse it doesn't backstab it's users and they give the choice to it's users rather than dictating it like dictators. So did I make a mistake switching to firefox? Is firefox becoming just like chrome now? or is there (hoping so much) and option given us to turn off the notifications as well?

I'd like to use the Startpage search as my default search in Firefox, instead of Google. And I mean the keyword-less search. I know what a search keyword is and I use several for special search engines (map, Wikipedia, dictionaries, parcel tracking, etc.). But the default search must work without any keywords.

And I want to use the custom settings they provide as URL parameters. I've tried with the cookie option but the cookie expires even after regular use. So the custom URL is the only working solution. Startpage support recommended me doing that.

I know that I can install the Startpage search to Firefox and it worked. But I can't combine it with the custom settings. So I uninstalled the extension, deleted the search engine and went to my custom startpage.com URL. Right-clicking the URL bar allowed me to add the search engine from there. But it also doesn't have my settings.

I couldn't find the search URL in about:config. Where is it stored? I need to change whatever Firefox thinks is Startpage's search URL to include my settings.

Changing the settings is critical because by default they open clicked results in a new tab which I cannot stand. I have enough open tabs, and there's still the back button.

Hello. I noticed that Firefox (98.0.2) doesn't even ask if the file should be saved or opened with a program when downloading some file types. Unfortunately, these file types (e.g. GPX) are not listed under Settings --> General --> Files and Applications, so that I could assign them to a program or specify that they should always be asked. And I can't add these files somehow... I have also deleted the file "handler.json" in the profile folder, hoping to be asked then. But that doesn't happen. GPX files, for example, are assigned to the GSAK program in the system - but Firefox just wants to save them and doesn't offer the option to open them directly in GSAK. Does anyone know advice how I can get Firefox to give me the choice? Thanks a lot.

I stopped using Chrome a while ago and I use, ahem, Bing for searches. Sometimes, when I click on a link I get a "404. That’s an error. The requested URL was not found on this server. That’s all we know." while using Firefox. I copy the link and paste it into the browser Edge and the site comes up no problem. Does firefox used a cached version of Google while Edge does not? Is there a way to resolve this?

I decided to stop using Google some time ago so made the full time change to Firefox and a different search engine. A tad bothersome that Google is still there. Not really interested in going to MS Edge...
