Firefox 技術支援討論區

I'd like to add Firefox to Adobe Dreamweaver for site design viewing. When searching Windows for Firefox.exe I don't see it in Program Files or Program Files (x86). Firefox is installed and used daily. Can someone tell me where it's located in Windows 10?

Spell check doesn't work I have been through the forum and tried the other solutions but noting works. Have ticked box in options under 'language', have added dictionary to Firefox, no dictionary option appears when I right click in text box. Spell check doesn't work on email, Facebook or anything!

Anytime I try to use Netflix, a yellow bar appears that reads "Firefox is installing components needed to play the audio or video on this page. Please try again later." I have read that checking to see that if DRM is ticked. I have unticked and re-ticked that option and still nothing works. I try and see if Widevine Content is being installed. All it says, and it always says that it "..will be installed shortly". I have looked around and some people recommend to install Widevine manually, but it is confusing and the links don't work. Please help, I want to use Firefox since I get some weird lag on videos on Chrome.

Every time I click a link, Firefox opens two (2) windows. One with the URL link and one just with my FF home page. And fixes with easy to follow steps? Happens with both my MacBook Air, the old one and the new one. Both are running OS Catalina V10.15.2

Thank you!

I exported my bookmarks from my Win7 laptop (via FF Quantum). Exported it onto my Win7 Desktop, with HTML extension. Then pasted it to Flash drive.

Note that when pasted, the file displayed as a Blue I.E. Explorer icon.

I then switched to my Win10 laptop, and pasted aforesaid HTML file into My-PC Documents. I then clicked Bookmarks / Show-All-Bookmarks / Import-Backup / import-bookmarks-from-html / this-pc / documents

then i clicked on the bookmarks.html file ...it displayed in the textbox. ......but then it stated "no items" in the grey area below where it states "Names Tags Location"

Please see my attached pic.

Hi

Running Firefox 71.0 (64 bit)

Well seems Firefox has been messing this up again.

Anyone have the new work around solution to get my tabs back on the bottom again. They were fine this morning then shut down and went out to lunch and when I came back they were back on the top again after months of being where I wanted them below my bookmark bar.

Thoughts on this?

Thanks Dave

There seems to be no way to set exceptions to privacy and security settings! There is a "Search Website" box but no option to "Add". There are options to "Remove" which are greyed out. I do I add an exception to Autoplay "Block Audio and Video"?

In Outlook for Office 365 if I click to view an email in a web browser, it opens in Internet Explorer 11 or Microsoft Edge, neither of which I want to use. I haven't found any way of changing the default to Firefox. In the Office file association wizard I ought to be able to associate the file types .mht, .mhtml, .url etc with Firefox but my options seem to be locked down within Windows 10 Home. 'Choose where to get apps' is set to 'anywhere' but I'm forced towards the MS Store where Firefox is not acknowledged as an app. Surely I can solve this without having to switch to Windows 10 Pro? Grateful for all help.

Hello. In my bookmarks library I have a lot of folders organized in a tree with multiple branches themselves organized in hierarchic levels. Sometimes I don't find the bookmark I want to use by browsing my tree, probably because I didn't put it in the right location in the tree. I can find it by the "Search bookmarks" function but this function doesn't provide the bookmark location in the tree (and I don't see any other way to locate it). Thus I can't correct the bookmark location error in the tree.

Is there a way to locate a bookmark in library folders tree ?

Web pages are loading painfully slowly, 11-34 seconds, some never load before timing out. Other browser (Edge) is loading pages quickly. Internet connection reasonably fast (35.7 Mbps). I tried the following:

  - Safe Mode, no change.
  - Refreshed Firefox, no change.
  - Disabled Antivirus and Firewall, no change.
  - Disabled Network Proxy, no change.
  - Content Process Limit set at 8.
  - Firefox is using 550 MB of memory (out of 10.2 GB)

There are instances when Firefox does load pages quickly, but they are increasingly infrequent and not predictable.

Using Options>Colors>I changed the background to "Black" and left the font "White", which was the default. I wanted ONLY the BLANK homepage black. I have a dark theme made by MaDonna. Immediately something altered, FF blinked (so to speak) and next ALL pages are a black background, including ALL webpages. Using FF instructions, I got back to a white blank homepage, but all the webpages have remained black. I've tried every combination (shown on your instruction page) to get back to a "white" background on the webpages. The "Always," "Never," only on ?? themes, clearing cache, returning to defaults, & I can still change the BLANK HOMEPAGE to either black or white, but nothing changes the webpages back to their normal views - white backgrounds. The only thing I haven't done is remove all cookies, because I truly do not want to do that.

Since the new update, tabs are on top again. And the fix for the last time it no longer worked (as usual) is not valid anymore. What must I do now? And why is firefox so set on placing the tabs on top? Thanks

I have account, where i have passwords/logins, bookmarks, etc. Some days ago i as usual reinstalled my Windows, installed Firefox, and tried to Sync. Sync was done, i pressed Sync on Account button, and nothing happens. Then i tried to see my pass/logins there: about:logins , but there is empty. And my bookmarks doesn't show.

How can a get back my logins, passwords, bookmarks, plugins?

Got updated to FF71 and my Tabs which I had moved under address bar got moved back above the address bar. (Had moved them under by creating userChrome.css file which no longer works) Is there anyway I can get the tabs again to display to under the address bar? It's just so confusing with the tabs on top. I appreciate any help!

Trying to get the sync to work with this laptop and my iMac, too, not just with my cellphone. But when I click to connect with another device, it only offers a window to put my cellphone number in, which is already synced!! How am I supposed to sync to my other computer, without going round & round in circles???? The image below is the only thing that opens when I click on "Connect another device"...

IS there a way to disable Switch to Tab PERMANENTLY? IT would be SLIGHTLY less annoying if it REFRESHED the old tab when it brought you to it. But for some really dumb reason, it doesn't. I don't want to have to remember to press Alt every time because I literally can't think of a single time I would ever want it.

With a Macbook Pro running Catalina (10.15.1) and Firefox 71.0b5 (or older versions) If FF is open on a second monitor connected via display port (I have 2 external monitors and built-it), when you Secondary click (AKA right Click) the context menu will often appear on the main Mac display rather than the monitor running FF. Also as the screen are different resolution the menu uses a smaller font. I have attached screen shots showing the two monitors. Assume this a FF bug?
