Firefox suddenly has become very slow. It takes too much time to load all websites and even the typed words and scrolling has a great delay in appearing. It becomes unresponsive very often. I tried reinstalling it and even reset it. Its becoming a pain to use this to surf the net. Please do help!!

This evening when I opened firefox, all the tabs from my previous session were there, but all of my bookmarks and history had disappeared. I received an error message, and tried all of the troubleshooting advice on this age: https://support.mozilla.org/en-US/kb/fix-bookmarks-and-history-will-not-be-functional I then tried resetting firefox, and so now all my tabs and theme are gone, but still my bookmarks have not reappeared. I have tried manually creating a new profile, and copying the old files, but that doesn't work either. My firefox is technically out of date because I have an old computer, and I know this might be part of the problem. But I really just want my bookmarks back! Thanks for your help.

Keep getting pop-ups on my computer. Contacted one of the companies the pop-up talks about. They have confirmed its not them and told me it sounds like I have spyware in my computer. They have advised me to download "adaware" or "spybot" search and destroy program, to scan my computer with. I would like to know if Firefox has something I can download ...thank you very much

why this error display "Adobe Flash Player has stopped potentially unsafe operation"

In message box following message display:

The following local application on your computer or network: null
is trying to communicate with this internet-enabled location : www.ajaxcdn.org

Basically I enter online competitions quite a lot and would like my details such as name and address to be recognized and remember after only typing in a few letters to save time. how do i do this?

power surge wiped out my LT video and external connections. I can see hd on network but cannot find out where the bookmarks are. Where can I go and get the book marks from the Firefox on my damaged system and move it to other LT I have? Firefox is latest version.

I like Firefox browser, but I can no longer use it on my one computer. It is an older computer, and the RAM is limited to a maximum of 512mb. Is there a reduced browser version I can run?

2nd question if you do not mind. I do have a newer computer I just purchased. I just installed your latest version of Firefox. Is there any way to reduce or limit the amount of "stuff" that loads on Firefox when it opens?

Thank you very much.

Sincerely, Richard

current program is firefox 16.0.2.0; message says update. when I go to update, it says to download 20.0.1 but does not indicate if I need to remove 16.0.2.0 first. I'm not sure how to proceed. Thanks

WunderMap time shows EST when page opens in Firefox 16.0.2. on iMac (Intel Core 2 Duo) OSX 10.5.8. When I open the same page in Safari, it shows the correct DST. Is there a way to adjust this in Firefox?

The issue of occasionally getting a redirect to "wyciwyg://(number)/http://(regular URL)" in the Firefox address bar, when trying to return to some previously visited sites, has NOT been fixed.

  NONE of the previously entered alleged fixes, are fixes, or they would work for me, and they do not. A "fix", would fix it, period! 
  My workaround: simply highlight the part preceding the correct protocol and URL, delete it, and the remaining address works.
  But no Mozilla coders have come up with a way to absolutely PREVENT this from occurring. And it is very disconcerting. Others had it happen for different but specific addresses for them, I have had it only for trying to return to my yahoo.com email address by any of several methods. I have tried EVERY suggestion posted. It happens on two different computers running Win7: Pro32bit purchased retail, and Home64bit on a "stock" Dell laptop. I also experienced it on an XP Pro computer decommissioned last year.

(aka) "DrWattsOn" (i.e.: spelled that way deliberately)

Initially staring Firefox 16 takes a long time. There is no evidence that anything is happening (CPU, disk, or task manager programs) for 15-30 seconds before the program finally loads. Once it is running, performance is normal. Other browsers and programs launch immediately, with no delay.

I have tried starting in Safe mode, using a new user profile, clearing and deleting the cache, running CCleaner, resetting Firefox, and reinstalling from scratch. Add-ons and extensions don't seem to be the cause of the delay. It is interesting that the delay also exists while loading the profile manager (15-30 seconds before it opens), and also before the confirmation dialog to start in Safe mode.

I am only using Windows Defender. The problem still exists when I disable real-time protection.

I would appreciate any help getting Firefox running up to its full potential!

I want to download Flash player i save it to computer but the download stops at 99 i reinstall window and delete all files ,i have no antivirus,i have zero security firewall is turned off all files of other format can be downloaded easily but some .exe files stops at 99.PLease help SORRY for my english . i am pakistani

Two questions please... First one is above for the tab function. In Safari I just need to press control+option+tab to indent a tab within a text edit box on a website. This function is being used more via cloud and mobile capability.

Second... I can, in Safari, Copy and paste a site with tables. Works great in Safari. When I try to do this in FF I lose the formatting of the tables and it just give plain text without the tabled fields.

I would love to use FF because the compatibility if much greater than Safari, but... I need my functionality as well to do my work to the best and quickest ability.

Thank you

I keep getting error messages it gets worse everytime Firefox is updated but lately it's 20 to 30 times a day..I have tried all the suggested troubleshooting methods nothing works..I even tried it in Safe Mode it mainly happens on Facebook on all pages and especially when I try to play my Farmville game I don't know what to do any suggestions from anybody??

Have uninstalled Adobe Flash Plug-in and reinstalled latest version. Had recently downloaded FF 19.0.1 and when I did a System Restore to last week which was before this problem started, went back to FF 16.2. Checked and all my plug-ins are up to date. Don't know what else to try. Please help!

P.S. Didn't update FF previously because I was trying to retain Red Cats with Green Flavor add-on.

I have looked and haven't found anything on this subject. I'm using Firefox 16.0.2. on a Windows 7 system. I get these ads in a banner covering the bottom of my screen. If I click the "X" button, it will disappear for a little bit and reappear. If I click the "disable" button, it'll appear as a side bar and it doesn't have a "disable" button on it, just an "about this ad" button.

If I click it's "X" button, it reappears as a banner at the bottom of the screen. While the ad is in the side bar position, I get this annoying banner at the bottom saying "related: ".

How do I disable this? It's annoying and I get enough ads on the websites I search.
