Firefox 技術支援討論區

Hi all, the shortcut to close a single tab (ctrl+W (Windows) or cmd+W (Mac)) is not working anymore.

here is what I tried so far: - disabling all extensions (via restart in safe mode) but to no avail - reinstalled Firefox but the problem persists - verified, that the command is indeed cmd+W and was not changed by accident - all other shortcuts are working well

NOTE: I can see that when I press cmd+W, the "file" tab up above on the Mac menu bar flashes for a brief moment, as if the system detects the shortcut. But the tab stays open.

Any other ideas I could try out?

Hello everybody.

I have created the following rule in user chrome:

/* Brings Back The Original Statusbar At The Bottom Of The Screen */

1. browser-bottombox { height: 20px; border-top: solid 1px #CCC;}

I'm really happy with this, except for the fact that it is visible all the time, so also in full screen.

Q: can I put a command in front so this hides in full screen? Been looking, trying for ages now.

Many THANKS for all your help!

Hi, I just discovered something odd. Trying to troubleshoot something with an android app communicating via web and laptop to free up the phone, and the relevant website has a chat popup and Firefox won't open the popup. I added the website to the whitelist and saved, but still wouldn't. Tried troubleshooting mode, but nothing. Switched to Chrome and it works fine. Cleared cookies and cache and restarted Firefox, but still no luck. The website is ExpressVPN.com. Macbook Pro OS10.14, Firefox up to date, version 115.1.0esr (64-bit).

Is there a way to disable the keyboard shortcut Command-Shift-Delete on MacBook so it doesn't open the clear cache dialogue box? I use this keyboard shortcut all the time to empty my trash; I've occasionally accidentally triggered it in Firefox when I was really just trying to empty my trash.

I reset my privacy settings to "standard", as they were causing too many problems. I quit Firefox. Some websites (like Google) are still telling me that cookies are disabled, when they are not and don't allow me to go to these websites. I attached 2 screen captures. Any reason for this and how to fix this problem?

Thanks.

I have Mac OS 10.14.6, so Firefox stopped working with its latest update. So I downloaded Firefox ESR. I want my passwords, history, and browser data from my original firefox, but when I go to the Import Browser Data function, my original firefox is not listed as an option to import from. And I can't launch my old firefox in order to export the data to an html file. So what can I do? Thanks!

I searched in Google and this website for instructions for how to delete specific cookies for a website. Many instructions are probably for older versions of Firefox.

I used to be able to login as of this morning to Wizzair.com. Then suddenly, regardless what I do, I can no longer use Firefox to login. I used the Preferences/Privacy & Security/Cookies & Site data/Manage Data for Wizzair.com to remove the cookies for the website, but it didn't help. I changed the password, it didn't help.

Their chat support sent me to their Privacy statement. There, there is custom list of cookies that they use. I was told to try to delete them individually... I have no idea how to do that and I could not find a method that works.

I can login the website using Safari. Any suggestions for what to do to be able to use again Firefox to login into this website? Thanks in advance.

I can't figure out how to delete this extension: Adobe Acrobat. It's disabled, but I want to delete it.

I want to know what caused the Firefox icon to disappear from my dock and be replaced by the generic icon. Firefox seems to continue to work well. I don't want to re-install it when it seems to work. However, I want to know what caused this to happen and if there is an easy way to restore it to the unique icon. I've read about the various remedies but don't want to take the time for a re-install when everything seems to be working.

Please just tell me the cause and if there is an easy solution.

Hello Team,

Firefox does not play well with how you customize keyboard shortcuts on Mac i.e. Go to System Preferences > Keyboard > Keyboard Shortcuts.

By default - Move Cursor to Address Bar - Cmd+L Bookmark this Page - Cmd+D

I would like to switch these two shortcuts but there does not seem to be any way. Please help me out.

Thanks, Naman

I am trying to print specs for a computer (beck & front) at:

https://www.dell.com/support/manuals/en-us/xps-8960-desktop/xps-8960-setup-and-specifications/back?guid=guid-f2dda353-ba5a-44c0-b85f-6bf1b8c70d15&lang=en-us

The print-out with Firefox captures only half on the picture and relevant info. Luckily, Safari prints correctly. I am wondering why can't Firefox do the job so I do not have to go to Safari for printing? This issue is not specific to this website, it happens often in many other cases. Is this being worked on? Thanks.

Where did all my saved logins and passwords go? Why did Firefox delete all that information? And NO, using about:profiles to check for alternative profiles, etc., does not work! There is NOTHING there! VERY DISAPPOINTED!!! This is going to cost me hours/days to fix, unless I can find out what happened and get all that info back!

I've used Firefox for years on my iMac with its 5K display. The UI was fine. Today I had to delete and then re-install Firefox because the program had started crashing repeatedly. I lost a lot of bookmarks & tabs. Upon opening the new install, I saw that Firefox now shows a miniaturized UI that is very difficult to read. I refer to the UI elements (tabs, bookmarks bar, URL/search field), not the web pages themselves. As part of the installation, I went through all the settings, and I didn't see any controls for the sizes of UI elements. So I searched the internet and found many reports of similar problems over many years. I tried a few suggested changes to about:config settings. Nothing has worked. I am exasperated. What am I missing? Can anyone help?

At some point, I've noticed that certain behaviours expected to occur when pressing the Escape key no longer did. Those behaviours mainly involved triggering some Javascript, including functionality in keyboard-related extensions, such as Tridactyl. Browser-level functionality on the other hand, such as pressing Shift-Escape to open `about:processes`, or pressing Escape to close Search Suggestions when the URL input bar, continue to work as before.

Upon investigation, I found it is specifically the javascript Keydown event that isn't being registered, while the subsequent Keyup event still is. I used https://w3c.github.io/uievents/tools/key-event-viewer.html to test this.

I also found that starting Firefox in Troubleshoot Mode (Safe mode) doesn't resolve the issue. On the other hand, creating a new profile does.

I've looked at the modified settings in `about:config`; there's a lot, but nothing stands out as being related to keyboard input or javascript.

Can someone please help me find what is causing this?

Since update 106, there is a new dock icon for Firefox on MacOS tailored for Big Sur an above. I'm still using Mojave for 32bit apps, and it doesn't look as good. Can we have an option to revert back to the old dock icon?

For years I have used Firefox and every update has been seemless. This one is terrible!!

Every time I click to open a new tab, it opens a new page Every time I try to change tabs from previous to the update, it will not change. I am stuck on that tab Every time a new page is created I cannot open it because it has a "block pop up windows" and this is a setting that I did not change. I have had to turn off all blocking just to be able to change my password, to be able to typoe here.

You have basically stopped my studies until this can be rectified and I doubt anyone will repond to this message
