Hi, I'm a very happy long time Firefox user. I use the extension "Dark Background and Light Text" so that my webpages are much more easy on my eyes. The extension works everywhere but in "support.mozilla.org".

How is it possible to have dark theme in Mozilla's support pages too?

Thank you very much. Prayan

After an update today, private browsing windows now are a different color than the other windows. I don't want them to be a different color. How do I change them back to the same as the other windows?

Also, how do I remove the extra text label next to the private mode icon, and just generally put things back to the way they used to look?

'recommended by pocket' option not visible in about:preferences#home, not in new tabs

I am unable to get the 'recommended by Pocket' panel to appear in new tabs with my normal user Firefox profile (Firefox account sign-in) on Mac Catalina. When I go to about:preferences#home the option simply is not present.

I created a new user login on my mac to access banking and other financials. This uses a separate Firefox profile (including new Firefox account sign-in and email), and the 'recomended by Pocket' panel is present.

The panel is present on new tabs opened for my normal Firefox account sign-in on my iOS (iPhone) Firefox install.

The about:config settings searching for 'pocket' appear to be the defaults, and match the settings in the financials account.

I have tried in 'safe mode' (add-ons disabled) and have done a Firefox 'refresh', however my add-ons (and presumably everything else) were restored when I signed back into my normal Firefox user account.

Hovering over the Pocket icon in the address bar displays 'save to Pocket', implying to me that it has signed me into Pocket. I've signed in at getpocket.com. New Firefox profiles without signing in do not show 'recommended by Pocket' in either new tabs or the about:preferences#home configuration page, but I expect the functionality requires being signed in to a Firefox account.

Help or suggestions much appreciated.

Plainly speaking, I don't like the new address bar, how it auto completes my searches or the results it pulls. I didn't like it when it was defaulted to being on starting with version 75 but I was able to easily switch a few setting in about:config to fix it. Those settings no longer affect the address bar as of update 77.

The settings I had changed were:

browser.urlbar.openViewOnFocus browser.urlbar.update1 browser.urlbar.update1.interventions browser.urlbar.update1.searchTips

which were all set to false. I saw that setting "browser.urlbar.disableExtendForTests" to "true" might be the solution but, while it does stop the address bar from expanding when using it, it also stops it from expanding at all so the websites that would come up from searching can no longer be seen either (they are still called and using the down arrow will let me scroll through the results, I just can't see any of them). It also doesn't fix the results issue which I would say is the most important.

I would like to know what I need to do so that: 1. The results it shows me are no longer based on frequent visit (basically, the pre-update search system, as is they are scattered and look messy, pulling many different sites in a seemingly random order and it's not particularly useful) 2. It no longer autocompletes results (IE. "F" autocompleting to "facebook.com", this is always something that has bothered me regardless is context) 3. It no longer pops out/expands when in use (admittedly this is mostly an aesthetic issue but I still don't like how it looks)

Hi,

Since 1-2 months my Firefox address bar grows vertically to about 1.5 its normal size when I click it. I think this came with an update. How can I disable this? It's really annoying and unnecessary.

Hi all,

I am trying to customize my Firefox on Mac because the tabs on top interfere with the menu bar, thus I only want tree-style tab extension to work on the side, with the tabs on top disabled.

I followed this thread: https://support.mozilla.org/en-US/questions/1184674#answer-1028260 as well as this clear guide on how to create userChrome.css: https://www.userchrome.org/how-create-userchrome-css.html When I tried to restart the browser, I seemed to have been logged out of my profile, with all customization gone and a standard white (instead of black) menu. I deleted the chrome folder and it is normal again now.

I suspect the userChrome.css file should contain more than just the one line I tried to add: #tabbrowser-tabs { visibility: collapse !important; } ; Is there any location where I can copy my current intra-browser customization into the userChrome.css file?

I have always had PDFs set to "Always ask" is described here: https://support.mozilla.org/en-US/kb/change-firefox-behavior-when-open-file This hasn't changed. The dialog which asks what to do with the file used to have "Save File" selected by default. This was convenient, because this is usually what I want. However, the default selection has recently changed to "Open with Firefox", which I hardly ever want. This requires me to perform an extra step when accessing PDFs from the Web, which I do quite often. I am not aware of having done anything which would affect this, nor have I found a corresponding option to change it back. How can I restore the previous behaviour?

Any way to do this?

I'm already using Jscher's excellent UserChrome script to make the folders an attractive yellow, instead of gray. But can this be done for individual foders?
