Firefox 技術支援討論區

I was using Ctrl+K on some websites to do things like site-specific search, task bars, and so forth, but recently Firefox started capturing it for focusing on the search/address bar (https://support.mozilla.org/en-US/kb/keyboard-shortcuts-perform-firefox-tasks-quickly#w_search).

Is there a way to unbind `Ctrl+K` in Firefox?

The background on the homepage link shortcut boxes keeps reverting to black and text underneath to white on my off-white background when a new version loads. I've used Colors to customize the look of my firefox but can't find any control for that. Once a new version kept the boxes white and the text black but now it's back to black again. Where is the control to fix this?

Hello,

Recently I was forced to install some "stuff" on my work laptop. Unfortunately, I am not quite sure what they installed. I have contacted my IT department and all I've gotten in response is that "we haven't blocked any browser or sites."

Since this update, I find that Gmail will eventually show an error and when I go to refresh the page, the loading screen never completes. Additionally, Youtube will eventually declare that I have no connection and at that point I can no longer open new browser tabs.

I have updated Firefox, used troubleshooting mode, removed extensions, turned off ad blockers (uBlock Origin), and nothing seems to work—these issues always appear again eventually.

I would greatly prefer to not use Chrome, so if there is anything I can do to fix these issues I would be all ears to know what it is.

Thank you, John

Just now, I tried to use "Email Link..." under the File Menu and got a pop-up asking me to "Choose an application to open the mailto link." I have seen this before, several times, and usually fix it by going to Tools > Settings, under General > Applications, select "mailto" under Content Type, then select Gmail from the drop-down menu.

This time, however, Gmail is not presented as an option, in this pop-up. Clicking "Choose..." just opens up a Windows Explorer file-picker window.

I tried to fix this in Tools > Settings, under General > Applications. There, "mailto" just shows "Use other..." and if I click that, the "Select Helper Application" pop-up window is basically blank, with a message at the bottom saying "No applications were found for this file type."

I refreshed Firefox but it did not solve the problem.

I have tried to attached images but they will not upload.

I am running v100.0.1 (64-bit) on Windows 11

Why do I keep getting this message from my A/V software (Bitdefender): firefox.exe attempted to establish a connection relying on an expired certificate to si1.lunrac.com?

Apple maps make my life miserable. I can't stay with Firefox after decades of loyalty because it is not worth it. Why are you self-destructing? You have no method of changing the HORRID UNWORKABLE Apple Maps to something that works.

In order to more convenient drag-and-drop interface, I need a fixed fixed space in nav-bar like Edge. For now we can add a flexible space on it. But it's flexible and it will disappear when I use a side window. And I can't drag over titlebar-buttonbox-container Please help me. Thanks!

The browser takes extremely long time to start-up. Task manager shows that it's trying to pull some 200mbs of data at the rate of 0.5mb\s or less. RAM is fine. HDD is old, but recently defragmented and, outside of <this> particular issue - it's not a problem. System is dusty, but system is system. For some reason virtually any other program launches more or less just fine. A particularly heavy game can pull gigabytes of data in about the same time that Firefox is bottlenecked to kilobyte speed.

It's not a conflict of start-ups, I have only the driver necessities in there. it's not a windows start-up issue, the browser can take as much time even a minute after windows is loaded. It's not a (anti)virus. Because I don't use either. It's not some 15 year old Celeron trying to handle W10, FX8320 should be able to handle opening a web browser. It's not a ton of extensions, and it's not even Firefox accounting, it happened before I registered. From extensions it's only ublock origin and VPN.

My personal three guesses are:

-More than 3-5 tabs on average, but, last I checked, the tabs aren't loaded upon start-up. And power users have sessions of dozens of tabs. -100-200 bookmarks. Again, not sure how hard is it to read a text data, unless it also has to load some thumbnails or icons or whatever. -Software aging.(Latest stable firefox, updates are on, and it has been running far less than this 4 year old system)

Reinstalling the system isn't a solution. Nor is reinstalling Firefox. Nor is dumping bookmarks, because otherwise why bookmark them. I'd just like to know why is Firefox limited to kilobyte speed of initial page loading. It can't be a damaged HDD cluster, otherwise I'd feel it outside of start-up.

With my limited knowledge of PC - it's usually a random read issue. Because like every memory benchmarks(HDD and RAM) can show hysterical speeds when loading\copying some 50gigs of a single file, if it's a few hundreds of thousands of small files - it becomes random and tanks. But what I don't understand why does Firefox have THAT much clutter? Is it really the bookmarks?

Used Firefox for many years with the inbuilt Microsoft on screen keyboard without problem.

After updating Firefox a couple of days ago to the 100 edition when I enter text in Google and press enter Firefox instantly crashes.

If I use the touch screen keyboard in windows its fine.

Using windows 10 fully updated.

Any help appreciated.

I had to remove my side bar to do a print screen. With the latest version of Firefox I can't find how to put the side bar back! Not Happy..... It use to be obvious but now it is too hidden. Who is doing the user testing these days? Please fix the issue.

I'm sure someone knows how to change pdf icons. I've only been able to change the shortcul icon (which doesn't need changing - microsoft didn't work its evil on it). Please share your expertise!

Using FF 100. Last week the Washington Post suddenly will not display article content correctly. Main page is fine, but when I open a story, I get code and a page with many blank areas. Story content appears with small print.

No problem in Edge nor Chrome.

Seems as if Firefox is updating every other day lately. I have Dashlane on my tool bar, and it seems to freeze/disable after every update. When I open Dashlane separately in the browser and log in, it congratulates me on installing it on a new device. What is Firefox changing with its updates that makes my computer look different to Dashlane? I cannot find the Dashlane version running but I do have it on automatically update.

Hi Since I guess Firefox 99 - not sure ... and now in Firefox 100.0.2 CTRL + Z and CTRL + Y not working when editing in Word Press ...

It is so annoying and make you loose data and waste a lot of time.

I cannot keep saving data all the time - yes I know Word Press has its own data saving etc.

I am talking about a 'normal' operation as CTRL + Z and Y !

I am a keyboard user since the 90s (!) and use loads of shortcuts fast and makes me waste hours sometime.

Any tips, maybe in the About:config settings?

Thank you M

I am currently creating a website in WordPress. It has many embedded YouTube videos.

On pages with embedded YouTube videos, in order to go back to the previous page, I have to click the Back button multiple times. If I right-click on the back button, I see that the page I am currently on has been listed multiple times.

Many other support questions list this issue. I have found that if I disable "Site Isolation" (URL about:config -> set fission.autostart to false -> restart Firefox), the issue goes away.

I am interested, however, in the user experience for those who will go to my site. Is there anything I can do so that "Site Isolation" does not cause this problem?

Thanks, Jeff

I just upgraded from a Windows 10 PC to a new Windows 11 PC. Under W10, the Home icon appeared in the top left of the screen, to the right of the Reload icon. But as you can see, it has disappeared. How can I get it back? I have clicked around all the options I can find, but nothing...

Hi folks, I had a problem with this back in June 2021 when my previously black background to the menu bar (bookmarks etc) changed to a washed out grey. Chris Ilias and dbben both replied, and Chris sent me a video guide on how to install Photon Colours, which fixed the problem, thanks. However, today the same problem has re-occurred - ie grey background. Unfortunately, when I checked in the Themes menu I found that Photon Colours is no longer there. Grateful if you could tell me if there is a new fix for this so that I can re-instigate the black background to the toolbar. Many thanks Chris

The photos page in OneDrive is having trouble loading most of the time. The page has the OneDrive header, and the section where the photos should show up is simply blank. Screenshot attached.

This is working fine on Google Chrome, but I would prefer not to use chrome for privacy reasons.

Can anyone help me with this?
