I'm using Firefox Developer Edition. I love Firefox. But when I change some CSS property colors on developer tools, it does not work instantly. For example, if I choose background-color it takes a little bit of time to show on web page. I'm front-end developer and sometimes I need to test different colors on my screens.

For my copy of Firefox, the bookmarks menu repeats itself as sub-folders ad infinitum: "Show All Bookmarks>All Bookmarks/Bookmarks Menu... /All Bookmarks/Bookmarks Menu... /All Bookmarks/Bookmarks Menu...." Each sub-level contains all the bookmarks of its parent level. Deletion of a "Bookmarks Menu" sub-folder results in deletion of corresponding parent folders and their contents.

Will allowing a Firefox "Refresh" create a restore point so that computer may be later restored to that point to view email account open at time of "Refresh'?

I went to an institution computer lab/3-D printing site in regard to printing (manufacturing) my patented product. During the interview I had to resort to my email about scheduling details and a pop up to "Refresh" Firefox came up. Being somewhat tired I allowed it. And being partly blind I failed to notice that my Yahoo email had the " Say signed in" in their default "Go" position. I signed out of my email but when I reopened the computer several minutes later,I noticed all my emails were there for anyone to read. Since this involved a patent situation, where IP stealing is always a problem, this was a concern. I logged out and was able to closed the email access only 10 or 20 minutes after the initial breach. But I wonder if the Firefox "Refresh" created a restore point so that a person with administrative authority on the computer could do a system restore to the point of Firefox "Refresh" and gain access to all my sensitive emails. Unfortunately the Yahoo default "stay signed in" often tends to put the user in rape- ready position. Subsequent refreshes or restarts may inadvertently leave the front door open for hacking of all your emails involving lawyers, accountants, mistresses, political improprieties etc.

How do I view the WHOLE console log, not just the most recent entries?

I'm trying to write a userscript and I have it writing to console.log so I can see why when something goes wrong. However, the console log routinely hides most of what I write to it. I can plainly see that, even though the script executes from the beginning, the log starts somewhere in the middle of the script execution, and vital information that I *NEED* is always cut off "above the fold".

I would be willing to settle for: 1.) Seeing ALL the console log entries my script writes, not just the small subset Firefox decides to show me 2.) Logging to a file instead of the console 3.) Using a remote logging service, if there is a free one that works (IE not Loggly). 4.) Running a webserver on my computer and logging via remote calls to that 5.) A way to use JSON.stringify to append the log to tags in the open web page... I actually had this working, but Firefox logs objects as "[object object]" so I can't see them. I already know they're objects, I need to see what they contain!

Any of these would work for me. I just need to be able to look at the log and see the order the various parts of my scripts executed in.

What would NOT work for me is:

1.) Using the script debugger. The problem I'm seeing is very sporadic, and my script uses jQuery, the amount of javascript that executes very quickly is really large, so manually stepping through script execution would require literally hours or days of tapping away, without even being sure the error will occur for me to see. I really need to just be able to use the web normally, and then, when the error occurs, being able to look at the log and see the script execution documented exactly as I set up my console.log commands to do.

The fact that I just spent the better part of two days unable to find a simple solution to the problem of just viewing my script's log entries, is making me think Firefox is not an adequate browser for javascript development. Am I making a mistake trying to develop on Firefox? Is Firefox no good for troubleshooting javascript on?

This is what I get. Is there something else I can use. I don't like edge or chrome.

File not found

Firefox can’t find the file at jar:file:///C:/Program Files/Mozilla Firefox/browser/omni.ja!/chrome/en-US/locale/branding/browserconfig.properties.

   Check the file name for capitalization or other typing errors.
   Check to see if the file was moved, renamed or deleted.

I would have liked Firefox more and sooner, if under History/Clear History When Firefox Closes/Cookies, the following was put on the page instead of just Cookies: "Cookies Including Allowed Sites." It is reasonable to presume that Managed Permissions protects cookies under all conditions, but this is not the case. Confusion in this area has caused me a fair amount of long term frustration and wasted time, and it was easily avoidable with a tiny bit more detail on this Options page.

I posted the below a couple of days ago and I did get a couple of suggestions as to how to fix that seemed to revolve around cookies. I found my way into a place on FF where I was able to 'forget' a website which seemed to fix the vegas.com site. However after trying to make a reservation on the site later in the evening the same problem appeared. Pick travel date particulars and the site skips over what should be the next twp steps (booking the hotel & flights) No amount of cookie and or history clearing seems to make the site work again. Seems to me that the security built in to FF is a tad too strict or something and keeps sites from loading correctly, Redbox still will not remember my log-in credentials from step to step while trying to rent movies on line. Anyone else have some suggestions? Disabling all Tracker / Ad Blockers does not seem to help either.

As before, these problems do not occur if I use MS Edge.

Since my move to a new PC running Windows 10 64 bit and with the latest version of FF a couple of websites that I frequent no longer work. They will work in MS Edge, but not Firefox. These two websites are Redbox.com and Vegas.com For Redbox their system can not seem to retain my login information during a session. Each thing I try to do asks me to reenter my log-in info. Can no longer rent movies. For Vegas.com, if I try to look at Air/Hotel packages the website always skips the pick a hotel and pick a flight steps and goes right to the option to pick a show to see. Again, this does not happen if I use MS Edge. What could be going wrong with FF new attention to privacy and security that is breaking these sites. I have shut off Content Blocking on both of these sites already.

Surfing Reddit, animated .gifv files, like those found on Imgur, will not load. Regular .gif files load normally and run. I have tried the about:config page, checked the image.animation_mode line and it is set to normal. I have cleared the cache. I have restarted Firefox in Safe Mode. I have the latest version of Firefox installed (currently 68.0.2). I checked Norton and nothing is set to keep these files from loading. I checked that the few Adddons I have are updated. My Extensions (Adblock, uBlock, Flash Flash player, Privacy Pass) are all updated. I loaded Flash video player. Nothing worked. Any other suggestions?

After re-installing my PC I also installed a fresh Firefox and added all my standard Plug-Ins. Everything worked perfectly fine with perfect stability. Then all of a sudden, probably after clearing History all these plug-ins disappeared from the toolbar and also don´t work (seeing commercials on youtube etc.). Only 1 Plug-In is still displayed and still works (NordVPN). I´ve been looking for solutions but didn´t find anything on this problem. There´s one fact that makes it a little special: all of the Add-Ons are in the Menu/Add-On Tab and activated, no problems appear. (Screenshot)
