On two different profiles, the Customize option simply isn't working. I see three different places on the GUI to click on Customize, and none works. Nothing happens when I click on them, beyond the letters "Customize" appearing at the top of a tab.

After appearing earlier this evening, the LastPass icon is also failing to appear on both profiles.

I need to deploy a customized configuration for a limited access network, and have created a custom mozilla.cfg file. It appears as though mozilla.cfg is not being read. I have intentionally created errors in the local-settings.js file, and it will throw errors (even when it cannot find the mozilla.cfg file). When I create errors in the mozilla.cfg file, however, no errors are thrown and no changes are made to the applications configuration.

Videos from YouTube I've embedded in a couple of web sites will not go fullscreen. I can go full screen on the same videos when on the YouTube site with no problem. On my embedded video the fullscreen control is there in the bottom right corner but I get the message "Full screen unavailable. Learn more." The source of the video is not blocking fullscreen ("allowfullscreen></iframe>" is included in the code), I've checked all my permissions, specifically for the web sites in question even, as well as my Add-Ons (I changed them all to 'Always Ask' in case some new one or update was bugging things up). What am I missing?

I have Windows Firefox 66.03.

Enabled Studies, and had "hotfix-reset-xpi-verification-timestamp-1548973" in "active" status. But I didn't have the second study! Nothing happened for few hours! So I tried to disable Studies and enable them again. After that the first Study became "completed" and no "active". The second is still absent. What should I do?? How to get the required Study and fix the problem? Can you help me please??

Just updated to Firefox 29.0 and the tabs not currently viewed are now the same colour as the background above them at the top. File, Edit, View, History, Bookmarks, Tools, Help are distinguished in a different colour though. I've checked but found this is the default theme. But it wasn't in 28.0, the tabs have always been a different colour to distinguish them. How do I tell Firefox to make the tabs a different colour to that above them? It's very annoying/disconcerting and just looks pretty awful. Not had this problem with updates changing the default colours before. Would have thought it's a no brainer for the default to have the tabs a different colour to distinguish them. Don't want to muck about with other themes, just want it like the default use to be. Thanks.

Hi - I need to use Firefox because an online course only works with it. However, I will never use it for anything else unless I can get rid of Ask.com as my default address bar search. I have been through the support files and have tried everything. There is no Ask toolbar. There is no chromewebapp.sqlite file or user.js file (may be wrong on spelling as I'm doing this from memory). I reset keyword.url and changed it to http://www.google.com/search?q=. I reset that other file (something about stone...again, I'm doing this from memory!). I reset Firefox. I completely uninstalled Firefox and reinstalled it.

I believe this is connected to Norton Safe Search. However, the Norton Toolbar is disabled and Safe Search is disabled. I did want to be able to use the Norton Toolbar and never had this problem with it in the past.

Can you help or should I just go back to using Chrome?

When 20 came around, I immediately got back the downloads window, 'cause, y'know, the whole download tab was just an awful, awful idea. "Oops, I accidentally closed Firefox while my downloads were still going!" "Never fear, the downloads window is still open, and so they haven't stopped!" "Nope, not anymore - how cool is that?"

Anyway, I digest...

Updated to 21, now the taskbar isn't showing the green progress bar for the downloads window, just %. Is there a way to get this back please? AND IF NOT, WHY NOT.

Thanks for your help!

In Firefox navbar at top of screen, when I click on "View" I no longer see "Reload page" as an option. I don't see any reload icon either. This just started happening today. I restarted Firefox, then restarted computer, but "Reload" is still gone from "View" dropdown. Is there some magic trick I've missed? Thanks.

I downloaded an add-on to have firefox reset itself every time I close and reopen it. Now I want to remove it, but it's not showing as an add-on. How can I get rid of it?

I cannot change the value in about:newtab from "newtab" to "blank." The dialog is displayed but when I click Ok, the value is not changed.

Comment on usual method and solution, by a forum Moderator.

As long as there are no confounding factors, such as certain extensions, or a user.jsfile the procedure is as follows

1. Open a new tab and type "about:config" in the address bar.
2. In the Search bar type: "newtab"
3. Locate and double click "browser.newtab.url"
4. In the "Enter String Value" box change "about:newtab" to "about:blank" and click OK.
5. Verify that the value has changed and now all new tabs will be blank.

My FF spellcheck works just fine, for almost all sites. But there is one site in particular (requires a login; it is a Moodle learning management system online class page) that must tell my browser not to use spellcheck on it.

Is there a script or about:config command I can use, to get FF to ignore this request, and give me spellcheck?

So...I checked my plugins this morning, and it said both my Java platform and my Java Deployment Toolkit needed updating. However, I click Update, and the link does not lead me to a download page. Plus, when I try to verify my Java version on the Java page, it says that I have the recommended Java installed (and so do other sites that run on Java). How do I update these things so that everything is up to date? Screenshots for further info: http://oi50.tinypic.com/15d87ly.jpg (the plugin checker status) http://oi47.tinypic.com/35jk0ub.jpg (What the "Update" link leads to) http://oi46.tinypic.com/34yz7kk.jpg (The verification)

I've seen this answer, but it doesn't fully fix the problem: https://support.mozilla.org/en-US/questions/951487

When I look at the address bar, I want to see the actual URI of the page I'm on, not some mangled version of it. In other words, I want to see the address in the form that is valid in an <a/> tag in XHTML.

Setting browser.urlbar.trimURLs to false fixes HALF of the problem, but not all of it. If I type in "http://example.com/filename%20with%20spaces.ext", I should see "http://example.com/filename%20with%20spaces.ext". However, I instead see "http://example.com/filename with spaces.ext". The "%20"s are converted into spaces, which are not valid in a real URI. How do I fix the address bar to show the real address of the page?

EDIT: It seems to me that if someone sets the trim setting to false, the URI should not be trimmed in ANY way. This includes the shortening of %20 to a space character. Is this a bug?

For those who are not happy with Firefox's removal of the downloads display progress bar in the 25 series, you'll be even more unhappy with the 26 series. Even typing about:config and isetting browser.download.useToolkitUI to true no longer works. I sincerely despise companies that DO NOT provide their users OPTIONS, OPTIONS. OPTIONS! Instead of pissing off a sizable number of people who prefer things the way they were. Stop changing things for the worst! I want to monitor my downloads progress without having to take an extra step by clicking on the "Library" tab. Who are you trying to impress?

I installed addons (e.g. adblock lite, ad killer) and when I shutdown Windows and start it again, the addons disappeared in Firefox. I'm using Firefox 40.0.3 non of addons will stay. I restored Firefox to its original state, installed everything again, also did the Malware scan as suggested on a post and the problem stays. So every time I start Firefox, have to install the add ons which is a bit hectic.

Please help me with some solution.

This is what I am looking at in the about:config

What can I do to fix this????

Hi,

I had applied the settings to disable the new urlbar features, but as of version 77 these no longer work.

I absolutely hate this change; it does nothing useful, it interferes with viewing the page, and it very much feels to me like change for the sake of change.

If someone can pass this on to whoever makes these unilateral decisions :

Don't make changes to the user interface that are not optional. How do they not understand that changing the UI for hundreds of millions of people is not a good idea?

So my question is, how do I disable the new urlbar "features" and return to a plain static one?

Hello,

I love FF and have used it for many years. However, every time I open it, I have to adjust the initial window size and then at least 1 more new window. I am using 65.0.2 64 bit on a Windows 7 machine. I was reading and saw a suggestion to use the command line switches to set the window width and height. So I made a shortcut with the target line as "C:\Program Files\Mozilla Firefox\firefox.exe" -height 850 -width 1800. This doesn't work. So what am I doing wrong or is there an easier way to accomplish this? I am very surprised that there is nothing in the about:config that would allow this type of customization. I also am baffled at what window size is presumed by FF.

Thanks for your help in advance!
