Firefox 技術支援討論區

I have been a Mozilla Firefox user for years, today I used CCleaner and since, have not been able to use Firefox as I wish. I downloaded a new Firefox Browser, installed it, was able to use it for a short while, but when I stopped using the computer for a while and came back to it, I can only get Chrome, and cannot get Firefox up and running again...I have even uninstalled Chrome in the control panel, but it is still popping up when I click on my Firefox icon!! Help!! FF is my default browser, has been for years!!

I have tried to attach a screenshot of Google on my computer, it won't let me attach it, no matter where I save it. How do I get them out of my computer? I need help!!

I have tried task manager, 7 instances of Firefox w/0% CPU, No instance of Chrome showing.

From our desktop and our laptop we cannot log into Workspace Webmail. We get error messages that the URL is Phishing. Tried from Firefox and from Chrome to no avail. On the other hand both of our phones can log into Workspace webmail no problem. Thoughts?

Firefox is displaying text in SOME windows so highly pixellated that it is unreadable. Other browsers display the same windows normally. This has been going on for a couple of months now. I really like(d) Firefox befo0re this happened. Since other browsers display correctly, I feel that it is not a hardware problem. Firefox also covers SOME graphics with green.bold text

Since the recent update to 89.0, I've been experiencing longer than normal initial page loads from start up or wake up for my MBP. Safe mode doesn't seem to matter, and it doesn't matter if a browser window is open and a page loaded or if I'm opening a new browser window, that first page load (or reload) takes much longer than it should (up to 10 seconds to load for example, the Google home page). Once I'm past that initial page load, my browser speed is fine. I also checked Safari and Chrome on this MBE, and neither have this issue, which leads me to believe it isn't a security or some other setting on the Mac.

Cursor jumps to toolbar address window instead of staying on the Firefox home page search bar. I prefer to use the search bar, without seeing all the urls show up in a list that changes as I type. This change occurred just a few days ago, apparently when Firefox updated. I have selected Google as the preferred search engine. (there are many other unwanted changes, but this one is the most challenging to deal with)

I'm trying to access a web page from share point for work but it keeps throwing me an error code. I can open the page fine in other browsers.

I talked to the administrator and he said it was a firefox problem.

Today I tried to log in to my HSBC account from Firefox 89.0.1, which I have been doing from Firefox for several years. The HSBC home page displays as normal, but when I press the Log on button I get the following message

Bad Request

Your browser sent a request that this server could not understand. Size of a request header field exceeds server limit.

I have rung HSBC, who say there is no problem at their end and I should try another browser, and the website works perfectly on Google Chrome. Why should this have happened, what changes have Mozilla made to the browser to cause this problem?

I already have to use Chrome to access my M&S Money account due to incompatibility between that website and Firefox. Should I change my default browser to avoid future problems?

I cannot add a Zoom meeting to an Outlook meeting using my Outlook Web app. The Zoom add-in is installed and the button appears in the Web app. When I click it, I get the message "Zoom is working on your Add a Zoom Meeting request." But it just hangs there.

The Zoom add-in works using my Outlook Desktop client on the Mac and using Outlook Web in Chrome. Firefox seems to be the issue. Any idea what I can try to fix this?

Some websites have this text box under their articles to write a comment and post it on Facebook (see the screenshot). But for that to happen, first you must login to your Facebook account. The problem is that when I click the button "login to post", nothing happens - as if I didn't click it at all. I suspect the reason for that are the integrated anti-tracking options in Firefox 89. So the question is: how do I get this plugin to work in Firefox 89?

P.S. Until a month ago I was temporarily using Chromium as default browser and there the FB plugin had no issues. Chromium has no anti-tracking options which is why I think this function in Firefox is the reason for the FB plugin not to work.

Here's the problem: when I try to play a Youtube or other video in Firefox, the sound cuts out after 1 second. Then silence.

I have tried everything. I updated drivers. I tried fixing sound in the sound settings. Nothing works.

This seems only to be a problem with the HDMI output, as it seems fine when I use Bluetooth. However, it is only a problem with Firefox, because it works fine in Chrome and Edge.

My firefox updated to the (horrible) new tabs, and now there's an incredibly annoying black line that appears over my Facebook tab that I can't find any way to get rid of. What does this mean? What is it for? How do I kill this stupid thing? With the (terrible) way the new tabs distinguish between the active tab and the inactive tabs (basically just a slightly different, nearly indistinguishable shade of off-white), this black bar is the most striking visual element on my row of tabs, so it grabs the eye the way the active tab should, and it's confusing and distracting.

I run FF on both a Windows machine and a MacBook Pro. On the MBP the browser does not save my tabs, despite "restore previous session" being selected. I do not have this problem on the Windows machine.

I have tried uninstalling and reinstalling the browser but it has not made a difference.

I'm running the latest version of the browser and the OS is Big Sur.

Today, whenever I close Firefox and then restart it, it brings up the tabs I had open last time before I closed it instead of my home page. I checked my settings and "Restore previous session" is turned off. How do I make it stop doing this and why isn't turning it off in settings working?

Hello,

I have Firefox 89 installed on my PC with Linux (Pop_OS!). The new proton interface does not change the bookmarks.

browser.proton.contextmenus.enabled is set on true.
