You give us no way to bypass these errors, I have used Firefox for year but am now looking at dropping it as a my Browser

All drag operations ( moving a book mark to the tool bar, moving E-mails to other folders, ...) crashes both Firefox and Thunderbird. I am running Ubuntu 16.04 with an NVidia card (Linux 4.4.0-78-generic #99-Ubuntu SMP and Nvidia-375 375.39-0ubuntu0.16.04.1) Firefox 53.0.3 (64-bit) canonical - 1.0 & Thunderbird 52.1.1 (64-bit)

When in Outlook/Live.com email the padlock is always green UNTIL or UNLESS I open CERTAIN emails & then it turns to yellow warning sign. SEEMS like it DOESN'T change (to yellow) when I open emails that ONLY contain writing ? Once it IS yellow it STAYS yellow - UNTIL I "Reload the tab"- so it goes back to just showing all folders, etc... with NO OPEN EMAIL. WHAT would I or should I change to make ALL email "secure". It also SEEMS like MAYBE any email with ANY picture changes it to the yellow warning. Or is this something that anyone shouldn't be very concerned about? It appears that LOT OF PEOPLE HAVE THIS "PROBLEM". And not only with the Firefox browser. This "green to yellow" situation has been with me, using Firefox as my default browser, for about as long as I can remember! A few or several years? NOBODY seems to have a SOLUTION! NOBODY! And I REALLY LIKE my email program so I DON'T want to use a different one. I tried Thunderbird but didn't care for it... but I don't remember if this problem showed up in Thunderbird or not. I wasn't looking for that/this, at the time. Thank you for ANY help that you might be able to give me.

when you click on bookmarks, you see your list of bookmarks

wonderful

but when you click to bookmark the current page it wants to put it in "other bookmarks"

I dont see a setting to change the default to Bookmarks

this is very frustrating ! ! !

This new security pop-up page is getting annoying!! Every website I try to go to, I get stopped with the security warning, even going to websites I frequent every day! I hope this list isn't coming from google! Please fix this. Thank you.

My wife runs firefox on a Surface with W10. When she opened it today the homepage looked like the control panel and a message was displayed at the bottom of the page that stated "Windows 10 Build is corrupted....". A dialog box displayed asking for login and password credentials. The only way to get out of this was through task manager. I uninstalled and reinstalled firefox and that seems to be working for now. However, this is the second time in a week that this has happened and I would like to know where it's coming from and ensure that it is removed completely from firefox.

The website shows text instead of the full page, clicking on things doesnt do anything, and embedded video won't play on any website that uses Vimeo as a source.

I have tried Safe Mode, as well as rebooting my system

firefox and thunderbird are not starting. Getting a crash on startup. tried safe mode --> same result (crash on startup) clean installation and removing profile didn't help ether.

I'm using a Flash player on one of my websites. It's a live chatbox, and whenever someone posts something, the box gets updated. You know, a typical chat box.

On my old computer, I had no issue with the chatbox. It didn't lag and worked perfectly. I just got a new laptop (HP Spectre) and so far the chatbox is not working properly on FF (works fine on other browsers). Whenever a new message gets posted, I can hear the "beep" sound that occurs when someone posts, but the box does not change to show the message. It's as if it is frozen. The only way to make it show the message is if I scroll through the page it is on, which then "refreshes" the box. I can type in the chatbox, but cannot see my text unless I keep scrolling up and down the page it is on.

I'm sorry if this is bad explaining, but I hope someone can help me with this. I've tried uninstalling and reinstalling Flash, uninstalling and reinstalling Firefox but nothing is working.

Hi, I'm not really sure what to do and it's been happening for a few weeks, but whenever I try and load Bandcamp it goes to a blank screen saying Firefox can't get to it and it shows that error code above, any solutions?

While i'm seeing videos from my wall or others wall and were on the same wall more than 30 minutes(more or less), on my firefox all page starts flashing in black or white, in other words i see all screen black, so i can't see the tabs but if i clic on correct position i can close tab. is there any cause of this? its quite annoying.

Firefox keeps crashing ever since the latest update. It doesn't matter if I'm looking at pics, browsing FB, looking at video, etc. It is CONSTANTLY crashing and I lose whatever I am working on. What the heck happened??? I never had this much trouble before. It was operating fine before the last update. Can I go back to a previous version????

PS- Tried to load file with crashes on it and would not load. I copied and pasted them below instead.
