Firefox Support Forum

I have developed a problem where by every time I go to certain web sites I am asked to turn on Javascript in my browser in order to continue viewing the page correctly. Whilst trying to find an answer to this problem I have discovered it needs to say under about:config "Javascript enabled" - default - true, but mine says default - boolean - true. Does anyone know if this is right and can anyone tell me what the correct settings should be so that I don't get the same statement on pages that really need Javascript ? Thank you.

Old printer (Samsung, listed in my Important Modified Preferences in Troubleshooting) will not allow new printer to be Default printer. No matter what I do. I've followed the instructions here in FF Help re about:config & reset and others too. Is this something to do with FF? I've tried to find & delete the old printer all over my laptop, but it stays there like a bad penny as the default anyway. Is there a way to get rid of it by changing a code or something? Never had this problem before. I would appreciate any help you can give me. Kindest regards.

i had bubbledock installing itself by stealth (yes i know better, but it happens) in my Ff browser. now i cant set anythingf as my default homepage.

i've tried:

A) dragging and dropping the "g" icon onto the home icon.

B) manullay typing the google url into general settings tab in options.

it would appear i need a slightly more advanced approach.

it may bee true that a reinstall may be simplest. however, i would rather educate myself in how to fix this.

many thanks to all.

Firefox is Blocking Flash and telling me that it's out of date and directs me to that Flash 11 vulnerability page. I'm running Flash 16, and when I checked for updates, it tells me I'm up to date. I upgraded from Firefox 34 to 35, and it didn't clear the condition. Flash is currently set to "Ask to activate" and the only available option Firefox will allow me to reset it to is "Never activate."

(Oh, and I took a screenshot of it, but it's not uploading.

I had to clear and restore my Macbook Pro and when I installed Firefox the drop down Bookmark menu is gone. I have the same version of Firefox on two computers and one has the drop down menu and this one doesn't. How do I get it back?

After the last Firefox update, lots of bookmarks disappeared, and I tried to restore a .jsonlz4 file. On the bookmarks manager window I choose the file, click on the Open button, the notice asking if I want to replace all the bookmarks comes up and I click the OK button.

I wait a while before using the browser again, but as soon as I click anywhere on it, it stops responding. I wait to see if it responds. Sometimes it does (but the same happens again) or a notice for a script comes up and I click on Stop the script. I try to uses the browser and the same happens. I always have to end the process on the window or with Windows Task Manager.

I restart Firefox and notice that many bookmarks are back, but far from being all. Some are also repeated, and others on other folders and many on a different order (!). Then I try to restore the bookmarks on safe mode, but always getting the same result.

What is wrong, and how can I restore the bookmarks, please?

it appears that one of the recent Firefox upgrades has broken my ability to connect to this website. I have seen no other issues with any other https urls. When connecting with a new browser instance initially get "Secure Connection failed ... client downgraded to lower TLS version than the server supports", followed thereafter by "The connection was interrupted" message. Clearing the cache does nothing, turning off the firewall (Bitdefender) did nothing, deleting the Firefox rule in firewall did nothing, cannot find any TLS settings in Firefox (35.0.1). Am I now screwed?

I'm using Firefox 35.0.1 and can't get the spellchecker to work. I've checked my settings and I have the option for spellchecker selected but zilch. I've even unchecked it, closed the browser and restarted it but still there's nothing. Can anyone offer any help or advice please?

Firefox has detected that the server is redirecting the request for this address in a way that will never complete.

   This problem can sometimes be caused by disabling or refusing to accept cookies.

Blocked did all I could think of. So I did the refresh and still the same crap!!!???

Have updated Firefox to 35.01, Checked add-ons, Firefox plugin check & updates said its vulnerable. Went through normal flash update procedure directly from Firefox link on the plugin check & updates. Installed update. Rebooted Plugin check & updates still says vulnerable. Checked Adobe website page, "You have version 16,0,0,296 installed" and it works fine. This is the latest version (as of 11.38 GMT 03-02-2015).

This issue has been previously raised, but people have been fobbed off with issues surrounding latest FF update and previous Flash updates which happened close to each other.

Any ideas ?

Adobe thinks its ok, so this must be a 35.01 issue or other FF compatibility issue.

i have just figured out after searching, that it is not possible to change my email for my firefox sync. it is already a nightmare for me that nokia email provider just simply closes down my account which i use for EVERYTHING in my life... i have somany account to change the email in it, but firefox sync doesn't allow me to do that. i really don't want to lose any details of my mozilla settings, so will it be possible to keep it with a non-existing email? or is there a way to open a new account with a new email and merge my settings to it?

I have recently encountered an interesting error with my browser, in that trying to update Flash to 16.0.0.305 (the latest version), the browser tells me it's already up to date on the Add-ons manager page. BUT then I go to Plugin-Check and it shows a "vulnerable" 16.0.0.257 Flash.

Plugin Check: http://puu.sh/fBNWT.png Add-ons Manager: http://puu.sh/fBO0d.png

The actual Adobe website isn't working for me and hasn't worked in over a month, it shows just a blank page: http://puu.sh/fBO53.png

I'm trying to update to alleviate a problem with a few websites I use that constantly show the "A script in this movie is causing Adobe Flash Player to run slowly. Continuing to let this script run may cause your computer to become unresponsive." dialog box. (Not a Firefox message, this is an actual Flash message.) It's annoying because I have yet to find out how to disable it, it's wrong because I know full well the website is optimized, and it freezes my whole browser for minutes at the time. Clicking "cancel" hangs the browser for a few seconds, and then the message just reappears. (Tested in Firefox, IE, and Chrome) Any Flash gurus out there with knowledge on how to completely disable this message...? I'm hoping that updating will help, but with no way to tell which version I'm actually running, I'm stuck.

All other web pages work, and hotmail works on IE. This has been going on a week now. If I try to get to hotmail through msn.com I get this message Secure Connection Failed

An error occurred during a connection to www.msn.com. The OCSP response contains out-of-date information. (Error code: sec_error_ocsp_old_response)

   The page you are trying to view cannot be shown because the authenticity of the received data could not be verified.
   Please contact the website owners to inform them of this problem.

I can get to my mailbox directly but it's not looking right, just some blocks of color and garbled mess. IE is fine, but I'd rather use Firefox for everything. OH, my other computers with firefox are also fine. Have run virus scan, no virus. Have cleared Firefox cache and lost all my passwords etc very irritating. But it didn't help. I don't think it's the Hotmail application since it runs just fine on the same computer with IE. Any ideas? Thanks.

Software: Windows 7 and Firefox 35.0.1 (previously 39)

Problem: When I open a window, I want to start a fresh browsing session. But Firefox instead reopens all the tabs from a previous browsing session. Seems like an easy fix, right? Well, I've taken a number of reasonable measures to fix this and it persists!

What I've already tried: I've selected the option to not reopen tabs on restart. Problem persists. I've selected option to delete all browsing history on close. This appeared to work, but when I changed the setting back, Firefox reopens tabs from before I told it to delete browsing history. Clearly it didn't really delete. I've selected option to go to my homepage on opening. It starts to go to homepage, but then replaces it with my old tabs! I've even uninstalled and reinstalled Firefox and THE PREVIOUS TABS ARE STILL THERE!!

Please help me if you can. This is driving me absolutely crazy. (Thanks)

Firefox has become slower and slower, so i 'refreshed firefox', something i've done numerous times before, but this time it cleared out all my bookmarks and all my history. i even had to re-register at some sites like i'd never been there before. For a while after that, when i opened firefox, it would open other windows with ads for off-the-wall things. I'd close them, and it finally stopped doing that, but it still is very slow and sometimes just drops websites out of the blue. Just now i opened a game on newgrounds and the game gave me a message that this copy of firefox had a 'bug' in it and suggested i use internet explorer or another browser to play the game. I am not real great at this stuff and i would like advice as to what to do. Thanks

I can watch Youtube videos as well as streams such as Twitch. However, when I try to watch an online movie stream it doesn't work anymore. The loading wheel just keeps spinning, but no error message comes up that says that there is a plugin missing. I installed and updated the flash player and shockwave player, so which plugins do I need more? Java or silverlight maybe? Thank you

Hello all, I am very confused and disappointed with using Firefox dealing with outdated plugins. Everytime I go to the plugin manager, I can easily see that there's a link that said "Update now". I was expecting to take me to the plugin's website prompting me to download the latest plugin, instead, I was redirected to one of your site that described why the plugin was blocked.

So in short, when I clicked on Update Now, I was expecting to go to a link from adobe website for the flash plugin, instead I was redirected to this website instead - https://blocklist.addons.mozilla.org/en-US/firefox/blocked/p178

Now can anyone tell me if this is a issue between linking to the correct website or just simply misunderstanding the word "Update Now"?

I also happen to find this link below very misleading; The instruction clearly stated that there's suppose to be a button that said "Update", but where exactly? On that webpage? In a different form window? In another website page? Please make this instruction more clear and understandable. - https://www.mozilla.org/en-US/plugincheck/?utm_source=firefox-browser&utm_medium=firefox-browser&utm_campaign=plugincheck-update

Regards, Regretful.

For some weeks now I have been having problems with both Firefox and Thunderbird. Neither will load. Sometimes I have been able to load once after a clean reinstall. I have tried: virus scanning and cleaning portable version on different computers (I use a portable version whenever possible but this has become an issue on static computers also) deletion of data folder

Just to rub salt in the wound, when the programs crash and I try to send a report, the error reporter says it is unable to send a report. Have not had time/patience to look into that.
