Firefox 技術支援討論區

Hello, I am a tinkerer and I would like to tweak my Firefox Developer Edition to suit my tastes, but I don't know what each of the preference commands does. Could you provide a list explaining what each command does and, if possible, how to use them? I don't want to reinstall Firefox.italic text I prefer to do things properly. Thanks

For months now I can't cut and paste if I use Firefox. I am not remotely interested is uninstalling a heap of adds in a vain attempt to fix the issue. I can use Google chrome and Wonderfox which don't suffer this issue. I fail to understand why Firefox is alone in this problem. I would switch to Wonderfox as a default but it only works on SSL sites. Please stop ignoring this issue and fix it. Running Windows 11 fully updated on an AMD cpu.

Recently my home page is blank. Each new tab opens as blank, bookmark icons are missing. I used to have a search engine when i opened Mozilla but now it's totally blank. I need to click on the bookmarks icon to open the list of bookmarks saved instead of seeing them on the toolbar. I didn't change anything and now it's all gone. I have uploaded a screenshot of my screen when I open Mozilla.

I'm running both versions of firefox on my mac by renaming the .app for nightly. However, when I click on a link on an application, it seems to default to my nightly version instead of release.

For both versions, the "default browser" setting is enabled. One thing I tried was letting chrome take the default again, and setting it from the release version after. Both versions then showed it checked again. I cannot uncheck it from the beta version.

It seems they might be reporting to the OS as the same app for this purpose.

Another thing I tried was changing the app name in it's Info.plist. Now, I see a new name in the menu bar and it shows as a distinct browser in the OS' "default browser" settings. However, it doesn't seem to solve my issue. All links still open in the Beta, even if the only one currently open is Release.

Is there a way to have it default to the normal version of firefox?

Firefox seems to forget edits made to text boxes. I was reading a large pdf and adding notes to previously made text boxes. I thought I must be going crazy as I saw there was no notes I thought I had already made multiple times so I tested it. I edited a text box, scrolled a bit and continued browsing on another monitor. Checked in a minute and boom edit gone. If anyone has a solution I'd appreciate it as I have been using Firefox PDF editor for a bit and quite liked it until now.

Hello,

I had a crap ton of pinned pages for a long time. I restarted my computer and now they're gone. I've restarted my computer before with no issues. Pinned pages are supposed to stay no matter if you turn off or restart. How can I go about getting them back?

Thanks,

Michelle Sinclair

System OS: Debian (codename: bookworm) Problem description:

I had installed a fresh version of Firefox and it's keeping to crash the pages (Error: The page has crashed) without any reason. Any troubleshoot methods (including clearing the cache, cookies, history and even restarted the network and pc.... only to fail and keep having same issue.

I had checked if there is no problem with the opened website in another web browser and in it the page was working correctly.

The issue persist from several versions of Firefox

Hi Guys! Huge fan of Firefox since the early 2000s when I first learned about it. Way more secure, efficient, and lighter than any other browser (IE, Chrome, and now Edge). Firefox is my first download on every new device and my go to even on my iPad.

I've been getting this error message lately and I don't know what to make of it. My saved tabs are working normally (email, work, streaming entertainment). This automatically comes out on ever new start / re-start (Firefox is my default) on separate tab but I am not opening any new website. It's been 2-3 days. At first I didn't mind it but its consistently happening and not just a one time thing. I already cleared my cache data. I've also ran a scan and it's come up clean (I have a paid BitDefender subscription). It's also not the local ip of my machine.

So any help would be great as I really don't want to leak any personal data or have any viruses.

Thank you for your time!

For years, I have used print to pdf in Firefox to generate pdf files of long web pages. It always worked. But lately, I noticed that huge numbers of blank pages are inserted in the pdf file, seemingly at random. I looked at the HTML source, and could not see anything that obviously triggers the blank pages. For example, a web page that ought to print to about 35 pages generates a file of more than 600 pages, with most of them blank.

I can use Microsoft Edge as an alternative, but pdf files from that browser strip out all the color, and are nevertheless super huge, about ten times larger than the ones from Firefox. E.g. the file mentioned above, about 35 pages, would be about 1.3 MB from firefox, and 12 MB from Edge. So getting the file from Firefox would be nice.

Is there a reason why print to pdf is behaving in this strange way, and anything I can do about it?

I have an issue where I go to website and I get a message that the website is temporarily available. I cannot go to a different webpage for what URL I want. I believe this has to do with history. I suspect I can get past this by flushing the history. I can get to the website I want by using a different browser such as chrome. Ho do I fix this?

IBM clone using windows 10, firefox 125

I've had an ongoing issue with Firefox now for several months since upgrading to windows 11. When I try to copy text, or images, url's or anything really that is supposed to go to the clipboard, it copies a blank text with no data instead. I can copy text and images from other programs and even paste them into text fields on Firefox but I can't copy from Firefox to anything else and it's frustrating.

I recently got forced into upgrading Outlook in windows and hated it so I started using Thunderbird and surprisingly, I have the exact same issue there as well.

I have tried: Running Firefox in safe mode (Shift + Left Click) Resetting Firefox Switching Back to default themes Disabling hardware acceleration Updating to the latest Beta Build (v126) Running Firefox Developer edition

I really want to get this fixed and working, I don't want to have to switch to another browser =/.

I am using Ubuntu 23.10.1 with KDE Plasma desktop environment. Since recently I've been experiencing the following problem with Firfox document viewer: after a period of inactivity, PDFs become unreadable, and seem to cumulate everything that was displayed on screen (see screenshot). Ctrl + F5 does not help, and neither does closing the window and opening a new one with a link to the file. KDE Document Viewer displays the same file correctly.
