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?

hey guys,

there doesn't seem to be an option for this. is there? if there is, I can't find it. see attached image for what I'm doing now. as it stands now, I have to manually push the DELETE button one time for every entry that is in that window for saved passwords. there has to be a better way to do this to get rid of all of them! can you guys help me with this?

I recently upgraded my Windows 7 laptop to Windows 10. Now in Facebook, videos won't play. I am using the latest Firefox and Flash player. The picture for the video shows up, but when I press play, it turns to a blur and won't play. I restarted Firefox in safe mode and the videos play normally, so it is an add-on causing the issue. I have disable each add-on, but can't seem to find the culprit. Maybe iI am not fully disabling them?

This raises another question...do I still need Flash Player at all? Do browsers now have other ways to play the videos?

Thanks in advance

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?

Everytime I restart Firefox, all my setting are lost and I must re-login. So I login, have to re-sync, click on view to add back my toolbar for bookmarks, and access preferences to reset download files destinations. I would like to restart Firefox and retain all these setting.

Please help. Thanks!

When I visit some musical instrument reatilers web pages (Guitar Center, Music 123, Musicians Friend, etc) the pages do not load completely. I end up with several portions of the page displaying a spinner.gif that says "Loading." Can some tell me what I need to get the pages to load completely? Thanks

Recently I bought a new PC, installed Firefox on it, logged in with my account and synced all of my bookmarks and add-ons, etc My wife is now working on my old PC, therefore I removed all old programs and installed just the basic stuff she always uses. She's also created her own account after installing the latest version of Firefox. I didn't rename the computer, only her Windows useraccount. Also created a new profile, that doesn't help either because bookmarks keep getting synced between two different accounts each on a different PC and I don't seem to get it right. Looked at the different devices that should sync under each account, that seems to be OK. But everytime I make a change in the bookmarks on one of the PC's with it's own account the other one also gets changed under that different account. Can someone help me by taking it step by step, so I can understand what it is I am doing wrong?

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!

I need a hard copy to transfer most of my passwords. Lockwise was installed on a recent update and I can only see one password at a time. Previously I could show all passwords and screenshot.

Cut & Paste is not working either within Firefox or when trying to cut/paste to/from Firefox to/from external file or document. There is no problem with other browsers.

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!

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 ?

Regards. j-p

As the title says I cannot play any videos on Twitter and have problems when I try to play videos on other websites. I cannot get Firefox to play videos in 60fps anywhere. Youtube won't even give me the option. 60fps doesnt work on Twitch.tv either. Playing videos on Twitch on Firefox is a nightmare in general. Super slow and laggy.

Neither of the above problems are there for me on Chrome. Videos work properly and in 60fps on Chrome.

I have already tried disabling hardware acceleration and have tried running Firefox in safe mode. Neither option worked. I'm getting kinda sick and tired of having to switch over to Chrome every time I wanna watch a video. Some help would be greatly appreciated.

HTTP://192.168.1.1 worked then I added SSL security and tested it using HTTPS://192.168.1.1. I had to add an exception to get back into the configuration page and I can't use HTTP://... anymore, any ideas why? I'm using the most recent version of Firefox.

Every time I start Firefox on my new Macbook, I have to login to my "Firefox Account" to get my bookmarks, passwords, and preferences. On my old Macbook Firefox is logged in whenever I open it. How do I fix this?

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.

Hello! I've noticed that for a while now, spam messages are being sent to my friend list from my Facebook account. I don't know if I did anything wrong while browsing but I've tried clearing the cache, the cookies and the history several times to no avail. Is there something I can do through Firefox to stop this? Thank you in advance!

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.
