I'm a web developer and I've been using the web developer Responsive Design Mode for some testing.

Unfortunately the default resolution is 320x480 and while I do occasionally test this resolution (it's our bare minimal mobile resolution) it's obnoxious to have to always choose the drop down menu to change the resolution every-single-time!

I've already searched through about:config settings for queries such as 320 and 480 separately.

So: how do I change the Responsive Design Mode default resolution?

I stupidly exported my Google browser bookmarks to Firefox when setting up on a new device and lost all my firefox bookmarks from all my other devices as a result. I am utterly horrified and freaking out - it's years of bookmarked articles that I'd even organised into folders! Is there any way to get them back?

When expanding any video to full screen mode, the video does not occupy the entire screen. However, if Firefox itself is in full screen mode, then the video will occupy the full screen.

I tested this on YouTube and another website's video player and was able to consistently replicate the issue.

For years I've set the background display color in about:config to a medium gray, #CCCCCC. Main purpose was to change the background color of the about:blank page, which is my home page and my new tab page.

Note I am not overriding colors; #CCCCCC only showed up as the bgcolor for about:blank. Occasionally websites which forgot to specify a background color would show up with a medium gray background, a minor inconvenience and a hint their coding was not so great.

Just realized my background color selection for about:blank isn't working anymore. The background color of the about:blank page is white. Not sure when it changed. I failed to notice when the medium gray disappeared because I have been reflexively pressing the dim screen button. I have vision issues and need to avoid a white screen.

There was a question in 2021 about the about:blank page bgcolor turning white which was archived but does not look resolved.

https://support.mozilla.org/en-US/questions/1344438

Does about:blank now specify a bgcolor, overriding my about:config setting? I still have browser.display.background_color set to #CCCCCC. Do I need to change another value for about:blank now? Thanks for your help.

I'm on Windows 10. Every time I open up a new tab, I cannot see either the saved links or bookmarks. It's like they have been wiped from the page. I can still access the bookmarks. I've tried the about:newtab and about:home fixes but neither have worked. None of my extensions are doing it, either.

Thanks for your time.

Hello,

I use Firefox since 14 years and I have a lot of bookmarks and folders, so can you do something to filter the folders in the "Manage bookmarks/Library"? My idea is to apply the word that I enter in the "Search Bookmarks" to all folders, can you add this option?

Example if I have a folder with the name "Hello The World", I would like this folder appear in my research if I enter the word "Hello" in the "Search Bookmarks" (Of course I also want to see the bookmark as currently, but I also want to see the corresponding folder(s)).

Hello, we are having an issue with one webpage we visit very often not displaying correctly on our computer screen using Firefox as the browser. We have used this page for 5+ years on Firefox and in the last few days it went from displaying 3 Columns to 2 Columns on Firefox (very annoying). If we look at this same website page in Microsoft Edge it displays correctly. We have tried various search options to figure this out with no luck ~ hoping this "community" can help us figure out why and what to do to fix this!

I have a problem accessing articles in the New York Times web page. I have a Basic subscription and I am signed in. When I try to read an article, the New York Times site thinks I do not have a subscription and that I have used up all my free articles. If I use the Chrome browser, it works fine, but I do not want to use Chrome. I use FireFox for all my browsing. I have deleted cache and cookies. Tried the "Private Windows" too. I have logged out and back in. I have rebooted the machine (an Alienware 17 R5) and closed and opened Firefox. The "agents" I chatted with say this is a browser problem as everything is working fine on their side and it works in Chrome. Can anyone help me out?

Hi.

After some time of trial and error I finally came to the conclusion that having the 'youtube.com' tab and 'antenaplay.ro' (tv broadcast app) tabs opened prevents my computer from auto-entering sleep mode. Even if the streams on the 2 tabs are paused.

I don't have this issue on Chrome, I can leave the tabs opened there and my PC can enter sleep mode no problem. The thing is I want to keep using Mozilla because I got used to it and because it's not based on Chromium.

If you need more information just say so. Thanks for the help in advance! Peter.

I run several versions of Firefox concurrently and recent added 102.3.0 ESR with no issues.

Backed Up bookmarks from a previous stable version to a .json file and imported to v102.3.0#

All the favicons were missing, replaced with a globe.

Visited a dozen sites to see if reloaded them but only 1 loaded icon. These are my own https sites with similar coding an NO code to hide icons - included google. No change.

Read all the posts I could. Verified databases, checked about:config BUT nothing changed, all bookmarks just show the globe icon. Even re-installed that version of Firefox, but same result. Started Firefox with an older profile from earlier version, for a rebuild. Same again.

Is this a bad feature of 102.3.0, an error or something else? Run 78.15ESR with same bookmarks and all are correct.

Any clues above all those published which do not work

p.s. anyone found a work around for THIS version to get green padlock back?
