I have a problem with Firefox, when I open gmail I always get the following message

Error

Some Gmail features have failed to load due to an Internet connectivity problem. If this problem persists, try reloading the page, or using the basic HTML version. Learn More.

to access my mail I have to reload the page at least 3-4 times

Any hint? Thank you in advance for any help you can provide,

We have high data usage, in fact in the past 5 days we've used 6 GB of data... I don't understand where this is being used. We don't upload/download much, rarely watch videos, etc. I'm just trying to figure out where this data is being used. On my laptop it states firefox has used 6.3 GB of data in the past 30 days. Is that high? Thanks!

Hi,

I am unable to print specific pages within firefox 44 and previously 41. These are mostly webpages from within my school system. Any time I try to print or check the print preview, all the content on the page is blank.

I went through all the trouble shooting on Mozilla support including 'Fixing printer issues in Firefox' and even went as far as doing a clean installation of Firefox (removing all files and user files tied to firefox). None of these helped the issue. I thought that it could be an add-on or my antivirus software. I went ahead and disabled those too and it fixed nothing.

I have isolated this issue to firefox as it does not happen in the latest versions of Safari, Chrome, or IE.

Any thoughts on what it may be?

I'm running Fx 44.0.2 on Mac 10.11.3. I believe the problem started before I upgraded though, but can't be sure. I can't print or print to pdf at all from Fx but printing in other apps works fine. I tried doing a refresh as recommended by troubleshooting page & it didn't solve the problem. Since that time I've only installed 2 extensions (1Password & Tab Tree). There was also a recommendation to reset a setting containing print_printer in about:config. It doesn't exist. That may be the problem, but it doesn't say what the whole name of the key is so I don't know how to create it. There's also a recommendation for removing all print items from the prefs_js file, but it seems to me that the refresh created a whole new profile which would make this moot. Am I wrong? Any help would be greatfully appreciated.

Per instructions for the router, I enter the address 192.168.1.1 in the address box. I have to enter my username and password. They are correct but are not not accepted. The name and password are right -- they work with Internet Explorer, though I do get a message about an unsecure connection.

What do I have to do to allow this with Firefox?

I am receiving this error on a few sites, but only one that I can list at the moment: https://www.flexjobs.com

Secure Connection Failed The connection to www.flexjobs.com was interrupted while the page was loading. -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.

Firefox cannot access this site from multiple locations (both my home and my work). I did an SSL checkup of the site and they get a "Grade A" and looks like it supports all of the correct "current" signatures: https://www.ssllabs.com/ssltest/analyze.html?d=www.flexjobs.com

Hello,

I just reinstalled Firefox and I can't access Google or Yahoo websites. I get "Your connection is not secure" message everytime I try to access them. How can I fix this?

Greetings

Youtube currently loads as shown in the attached file. I tries safe mode, refreshing firefox, and clearing cache and cookies, nothing worked.

Thank your for your ongoing support.

After reinstalling Firefox (to new 64-bit version), I've lost all of my favicons. I'm seeing that only way to get them back is to individually select each bookmark. Is there a way to get the bookmarks to go and automatically download their favicons so my bookmarks will be repopulated again?

I have been downloading a file for two hours now and will loose my internet connection when I change locations. The file has three hours remaining. Can I pause the downloading so I do not have to start over again.

Sometimes when I open Inspect (alt+command+i) the frame is empty and the Inspect doesn't load. I'm using a Firefox 44.0.2 for MacOSX El Capitan and this a recurrent problem I had in other Macs. Does connecting from China could be one of the reasons? Here many servers are blocked so maybe a library doesn't load?

Please check the screenshot, any idea?

Thanks!

I have been having this issue for a long long time now , but for some reason firefox refuses to play the mp3 files on certain sites . http://hydra-media.cursecdn.com/dota2.gamepedia.com/a/a5/Alch_spawn_04.mp3 Example this one .

I do not have any technical knowledge as to know why does it not work , i have no clue what is causing it. Thing is , i tried installing chrome , same thing ... no sound either.

Im using Windows 7 , if thats any help .

I tried googling stuff up , found bunch of *solutions* saying to install stuff , but i cannot even install them on my pc .

So yeah , question is ... is there any way to play that files ? I keep stumbling upon embedded audio , and its not working and its kinda frustrating to say the least :/

PS: Stuff is working fine on my tablet ....

I have set my preferences so that when I type something into the URL bar it will use google as my search engine, yet lately it keeps going to yahoo. When I go to preferences: search: default search engine: google and it still goes back to yahoo as the default search engine. I'm not sure what else to do.

Firefox don't download files with the right name example:

'song.mp3' is downloaded as 'song'

If I rename the file adding the extension it opens. But that's annoying and I really do not want to have to do this with every file.

Tried recreating user profile, deleting 'mimeTypes.rdf' ...

I'm in Windows 10. Was using it well (I'm not computer literate) and after several months of doing so found that the minimize and expand toggles had disappeared. My Firefox version is 44. I've stepped through the following:

Trouble shoot and diagnose Firefox problems - have reinstalled, refreshed 
 Went to Support Forum and deleted the xulstore.json file (Have trouble figuring out how to close and restart firefox)

None of this works. I love Firefox and have been using it for over 5 years maybe longer. But I'm really frustrated as I don't have tech skills.

Any help even with the basics like exit firefox, close firefox and restart firefox would help. A simple close or exit firefox switch would simplify all this for people like me. All I want is my Firefox browser with its basic functions back. Paul

Firefox does not open my homepage since the latest Firefox update 44, it just opens a blank page instead. I have tried deleting the user file suggested in other posts, but that did not work.
