TEST''''is issue still there ?

i am not a techie. i am just a guy that uses a computer. why should i have to do any of the things listed?? i turn to IE or chrome and things fly. i prefer firefox but all of a sudden it just drags. nothing has changed on my computer, no new add ons....etc. i run several scans and keep my machine clean including clearing the cache.....it should just work!!!

Hi, if you prefer doing nothing that is fine. As for it should just work well the answer is it's a computer program and things happen like a corrupted file, malware that needs a malware scanner to fix things and not a anti-virus scan.

So you need to decide what you would like to do to continue using Firefox. Support Volunteers will be around to help you when you decide. Thank You.

as i mentioned before....i run avg anti virus, ccleaner, malwarebytes, spybot s&d and sophos virue removal tool.

i spend a lot of time on facebook and from what i am reading...i am not the only one having this problem!! but, of course, you would not no it because you no longer "monitor" your facebook page!!

so i would say it's not my computer!!!

Hi, you did not mention before that you had run all those programs.

i run several scans and keep my machine clean including clearing the cache....

as i mentioned before....i run avg anti virus, ccleaner, malwarebytes, spybot s&d and sophos virue removal tool.

As for Facebook Support not monitoring the page, I know nothing of that as I do not Volunteer there. If you have anything to share you can ask or post here : Feedback: https://qsurvey.mozilla.com/s3/FirefoxInput/

Ok, so it is not your computer. But it is your Firefox that is not working properly and there is no correlation between Chrome or IE if Firefox is slow. Did you try the suggestion for safe mode ? Have you looked at this :

• https://support.mozilla.org/en-US/kb/firefox-slow-how-make-it-faster ?

Am trying my best to offer you the support you asked for.

chrome works fine as does IE......this slowness really got bad after the last update!

Hi, well will need to turn a little techie to fix this as browser are no longer a simple thing to work on as of old. Please try a Refresh but Note that this does more than uninstalling and re-installing does. Normal uninstalling does not remove some preferences which may have become corrupt. Please Refresh but do this 1st:

• https://support.mozilla.org/en-US/kb/export-firefox-bookmarks-to-backup-or-transfer
• https://support.mozilla.org/en-US/kb/back-and-restore-information-firefox-profiles

then

• https://support.mozilla.org/en-US/kb/refresh-firefox-reset-add-ons-and-settings

TEST....... If no issues then Extensions which need to be added back in 1 at a time and tested ..... Or it is your Profile : Make a new one and test ...:

• https://support.mozilla.org/en-US/kb/profile-manager-create-and-remove-firefox-profiles

If is your Profile :

• https://support.mozilla.org/en-US/kb/recovering-important-data-from-an-old-profile
• http://kb.mozillazine.org/Transferring_data_to_a_new_profile_-_Firefox

Note: Any customization will revert back to default, you will also need to reinstall Extensions.

Please let us know if this solved your issue or if need further assistance.
