Firefox Support Forum

Hello,

I just upgraded to Firefox 87 and noticed that I wasn't able to go back to the previous webpage by clicking on the backspace button like what I have done in the past if I'm not using a mouse on my laptop and had to click on the back button in the toolbar with the trackpad. I'm not too sure of why that happened with the upgrade and was a little surprised about that. Hope I can be able to get around this in some way if one of you know anything about this. Thanks.

How I export my profile data from an extension? An extension I'm using isn't working properly and I'd like to export my data before reinstalling it. It's called onetab.

The menu on the top right corner is gone, so how can I export my saved data (or tabs)?

screenshot option is missing since WIN 10 20H2 update yesterday

Tried toggling true/false screenshot settings in about:config with close & reopen firefox inbetween

I finally turned off the menu bar some time back and started using the Bookmarks Menu Button (the little star with an underline). With v89, the dropdown menu from this is huge. The fonts are a lot bigger than in v88, and for some reason, there are now two "Manage bookmarks" items, one at the top and one at the bottom. Is there any way, either official or through userChrome.css, to choose a small font? I already have a userChrome.css that I used to remove items from the old Bookmarks menu on the menu bar, but those don't apply to the BM Button.

From the very start, for the last 25+ years, Right Click a link, and hit the letter W to open the link in a new window... Suddenly, with 88 Update, it is now the letter D. (while everything else in Windows is still W)

How do I get it back to [W] (Industry Standard is W)

Why did Mozilla change the letter to D?

I don't mind having to train myself to use D instead of W... I do mind that everything else still uses W, so I have to train myself to only use D in Firefox.

Hello everyone, i need help.

The "screen capture" from the "3 points" options on the address bar disappeared. I didn't change a single thing. Anyone knows how do i proceed with that to reactivate that tool again?

I'm so unhappy now I don't know where to begin.

I was having trouble loading a website (lowes.com), continually getting an "access denied" error message. It occurred to me that I'd read somewhere that if you told Firefox to "forget this site," it might solve the "access denied" problem. I didn't remember how to do this, though, so I searched online and found a site that said that adding the "Remove" button to the Toolbar and clicking it would solve the problem. I dutifully added the "Remove" button, then, before clicking it, I triple-checked that the "Forget the last Five minutes" was selected and not any longer period of time. After all, I didn't want to lose everything!

Well, I did.

I had literally hundreds of tabs that I was working on open — they're all gone. All of my history — years worth — is missing. More things may have been deleted, but, to be honest, I'm afraid to check.

What did I do wrong? Or is the "Remove" button buggy?

And while I believe that everything that's missing now is irretrievably lost, if anyone has a hack to recover anything, I would be so, so grateful if you'd let me know.

Thanks in advance.

P.S. I wrote this post up once, hit "Submit," then, after an interminable period of time, the screen went to a blank page. My original post has never appeared. Is there perhaps something wrong with my Firefox (which has been perfectly fine up until now)?

Hi, In continuation to this thread, https://support.mozilla.org/en-US/questions/1293344 , May i know if the decision to continue the support for Flash is still the end of June 2021 or has it already been decided to push until Sep/Oct end?

As described in https://support.mozilla.org/en-US/kb/diagnose-firefox-issues-using-troubleshoot-mode, you can hold alt/option key to start Firefox in Troubleshoot Mode.

It turns out I'm using BetterTouchTool app on macOS and I assign individual keyboard shortcuts to launch (or bring to foreground) each application.

If I assign a keyboard shortcut for Firefox that involves the alt/option key, Firefox will start in Troubleshoot Mode. That is described here: https://community.folivora.ai/t/firefox-starting-in-safe-mode-when-launched-via-keyboard-shortcut/8939/7

Is there any way to disable that behavior or maybe change that key?

I appreciate your answer.

Looks like SNI settings via about:config in Nightly don't apply. Nightly version: 90.0a1 (2021-05-24) (64-bit) OS platform: Win 10 pro, 21H1 19043.985

1. network.security.esni.enabled ->true 2. network.dns.echconfig.enabled ->true 3. network.dns.use_https_rr_as_altsvc ->true 4. network.trr.mode -> 2 5. in Network settings DoH is enabled and Cloudflare (default) is selected 6. 1.1.1.1 with WARP is used

British English Spell Check as you type is no longer reliable, sometimes it works but most times it doesn't. Can't seem to get to the bottom of the problem, all settings are correct but still doesn't work properly.

Hello i just made the update from version 88 to version 89 and i noticed, that the design of the Tabs was changed. Also the coulor of the title bar does not longer match my windows theme. I looked trough the new design and i must admit that i does not like that minimalism style at all. Is there any way to get atleast the colour of my title bar back to my normal Windows setting?

I just opened Firefox and discovered that version 89.0 is installed. I would like to know how to move the tab bar down below the bookmarks bar like I have always used in Firefox.

Thank you for any help.

Says that I can’t have lines separating my unused tabs anymore. This is SO annoying. Can anyone help me get borders between my unused tabs?

Also, WHY ARE YOU DOING THIS Mozilla? Now I have to stop EVERYTHING that I am doing and research how I can make your browser work the way I want it to. Why do you always assume that you know what is best for me?

I tried the "Stylish" add-in but when I try to install a specific style from their site - nothing happens.

The Firefox Universe is extremely vast, and trying to Google “lines between my unused tabs” is getting me nowhere. I don’t know how to develop themes. I don’t code. I just want the browser to look like it did last week. Is it really so much to ask?

Every. Single. Time. I update Firefox - I regret it!!!

The floating tabs are awful. They all mix together and look like one giant tab which makes it infinitely harder to find what I'm doing when I have many tabs open. The proton design is disappointing all around but these tabs are unacceptable.

How do I get rid of this crap? I either select a crappy system theme and everything turns a blinding white, or go back to the theme I usually use where everything suddenly is dark. How do I remove darkmode while retaining my favorite theme? I don't want dark mode and I certainly do not want to be blinded either. There must be a useless setting added to the about:config that I can disable.

Thank you.

The color scheme and the look of the browser are awful, and it's hard to see the plus sign to open a new tab. I would like to switch back to the previous color and style scheme (rectangular tabs and all). How can I do this?

I want to set 2 preferences regarding syncing as default preference for all (new) profiles. 1. sync toolbar layout. 2. set my own sync server path.

I already know how to do this via about:config manually per user. I want to have these 2 preferences by default for all users.

On Ubuntu 21.04, I followed these instructions to the letter, but it has no effect, tested on a newly created profile: https://support.mozilla.org/en-US/kb/customizing-firefox-using-autoconfig

I created: /usr/lib/firefox/defaults/pref/autoconfig.js And it contains exactly what is in the instructions.

Also created: /usr/lib/firefox/firefox.cfg Looks like: ``` // IMPORTANT: Start your code on the 2nd line defaultpref("services.sync.prefs.sync.browser.uiCustomization.state","true"); defaultpref("identity.sync.tokenserver.uri","https://ffsync.mydomain.tld/token/1.0/sync/1.5"); ```

Then I create a new profile and check via about:config, unfortunately the first preference doesn't exist (note it doesn't exist by default) and the other is not applied, I still see Mozilla sync server path.

How can I set these 2 customisations globally. for all future users (preferably also current users)?

The new update has way too much whitespace around the tab names and especially between drop down menu items. This is awful. Any way to set it back the way it was, through a customization perhaps? I don't see anything obvious in the options...
