Recently upgraded from Win 7 to Win 10 ad forgot to take back up of my Firefox bookmarks in Win 7 is there any way i can retrieve it? There is a folder called Windows.old that Win 10 has created in case to revert back to Win 7 in 30 days will this folder have my firefox bookmarks?

I freshly installed Windows 10 and I can't install Firefox inside "ProgramFiles (x86)" I tried running as admin, changing admin privileges but nothing worked, then I tried to install it inside "C:\Users\*username*" and that worked. Any ideas why this might happen?

I recently installed windows 10 on my PC and just found out i can't watch anything on firefox with the flash player plug-in, it doesnt crash but instead of a video, the screen is just green but there's sound, and when trying it with other browsers, it works fine. I've attached an image to highlight this...

I am using PINTEREST. The window/page where information is entered before 'pinning' has enlarged to supersize, no longer at 10%. That is the only place this happening. Where do I go to fix this?

tried changing homepage, blank, mozilla, others. When i close and reopen mozilla browzer the yahoo homepage is the only one that appears. It came with the mozilla download. I already deleted it from the settings, but it keeps popping up. I tried the suggested one on website.

I use my password to access my sync and everything else except the Mozilla support pages. Keeps telling me bad password.

I cannot delete the Unsorted Bookmarks folder (delete is grayed out, as is Cut) and it has literally thousands of entries. I rarely if ever use the star so they must be being added automatically. Most of the entries are "Real Player Home Page." I think this huge number of (useless to me) bookmarks is affecting the Sync function as it keeps telling me it has encountered an error.

Until recently I was using Xmarks but that, too, has stopped functioning.

I am at a loss as to what to do to get rid of all those bookmarks under the UB folder.

I am having trouble typing an email on gmail account, and on this site, the letters disappear and are partially covered with blank spots. My emails

I cant see what I am typing now! I can't see emails in my inbox clearly.

I am trying to upload a screenshot; but I don't think it is going to work.

Educated guesses seem accurate.

Thank you for your assistance,

I have replaced Firefox in Web Browser Settings in Windows 10. I boot Firefox and make it my default browser. When I search web sites in Firefox it does nothing. I tried it with Google, Bing, Yahoo - nothing happens. If I go back to Windows 10 settings and change it to Microsoft Edge, it surfs immediately with Bing. I have done this 100 times and it does the same. Very frustrating!

Since I downloaded Windows 10, I cannot open certain sites, like Yahoo, without turning off my firewalls. I know what the problem is, but I don't know how to solve it. Please advise.

I own the website https://vzinity.com which is running on Nginx and uses a Comodo PossitiveSSL cert.

I have tested the SSL installation at https://www.ssllabs.com/ssltest/analyze.html?d=vzinity.com and it gets an A+ score.

I have tested opening the site in many browsers but I only see this problem in Firefox. When I visit the website using Firefox 39 (Windows 7, Windows 8.1, Windows 10 and Linux Mint) I get the following error:

Secure Connection Failed

The connection to vzinity.com was interrupted while the page was loading.

Thanks.

I would like to set Firefox to open new tabs to the Start Page rather than a blank page, or the page with suggested sites and most used sites. I cannot find a way to do this. Does anyone know if it is possible?

Since W10 came out, Firefox seems to have been "purposely" sabotaged.

I repeatedly get asked to change my default browser off firefox, despite it being long set in place as such. It's running much slower, with many more errors. I now get seemingly continuous Screen updates, make doing emails nearly impossible as the screen freezes while it "thinks". I now get continued "(firefox not responding)" error messages.

Hope you can do some work-arounds. D

I got the windows 10 download and have so many new things I want to stay with Firefox but need to put faves & contacts on both browsers.

If you can give me some instructions on how to do this it would save me a lot of time!

It will be fun to use some of the new inventions they have but it doesn't feel like home. Thanks

I have included an image. Steps I have already tried are:

Uninstalling and reinstalling firefox.

Allowing websites to use their own fonts

Disabling Hardware acceleration

Nothing has fixed this so far.

Did not make nay backup of BOOKMARKS before re-installing windows.

Recently i had virus in windows, formatted C:/ Drive, and re-installed windows, forgot to backup Firefox bookmarks.

Can i get bookmarks back from MOZILLA SERVERS or something like that?

please HELP !!
