I used to be able to go to a website, click on the drop down arrow and see all the options, but now when I click on it nothing drops down and I have to use my arrow keys to see what is there. I tried this on other browsers and the drop down menu works, just not on firefox. I am running Firefox 50.0.2. How do I fix this?

Thanks!

I have some add-ons installed which keep disappearing from the top toolbar where I want them (next to the search bar). They include Video Download Helper and Self-Destructing Cookies. I entered Customize, and these add-ons are not shown in the "Additional tools and features". They are definitely installed as they show in the Add-ons Manager, but they are not at the top bar -- I have the bottom Add-on Bar Restored, and several of my add-ons do show there, but not those. There is no drop-down arrow indicating that they are actually there but hidden. They are not there. I'm assuming there's some kind of conflict, but I don't know what it could be. It doesn't seem to have anything to do with what theme I am using at the time. Thank you. using: Windows 7, Firefox 50.0.2

The HTML5 player controls will hide itself after a few seconds when a video starts to play either from clicking a YouTube video link or when the video is resumed from pause. However, the controls will remain visible as long as the video is paused. The controls are quite obstructive due to certain moments when I need to pause to see a certain thing in the video in a very short time-frame but got covered by the player controls and disappears when resume playback. So, how do I make the HTML5 player controls to also auto-hide a few seconds after the video is paused or instantly hides when the mouse is outside the player area?

That used to happen for years. About 2 months ago Firefox began opening with a 'restored' (i.e. not maximised) window. For a few days in the last fortnight it resumed opening maximised. Now it is opening with a 'restored' window which is wider and shorter than the size used previously.

I have determined that the the only proxy setting that makes my computer perform optimally is the "no proxy" setting. I have read, however, that this setting could leave my computer open to hacking and other intrusions. I am on a home network with no other users. My ISP is Comcast. I do not run any protective software other than what Windows provides and whatever protection a router gives. Is it safe to set the proxy setting to "no proxy." Even though I have a high-speed internet connection, I am unable to access most sites for up to 30 seconds and sometime I just get time-outs. When I changed the setting to "no proxy," I was able to connect to sites lightening fast. I have always thought it was Comcast, but it seems that it is this particular setting that is the culprit. However, if the "no proxy" setting jeopardizes my security, I will change it to another setting.

We are using calc() to calculate the width of columns in a grid with fixed width gutters, but the calculation is off by a weird number and it forces the last column to drop below the rest. At first I thought that this was similar to older IE's rounding errors, but it is not.

Example:

.delivery-slots__slots, .delivery-slots__day {

   width: calc((((100% - 35px ) / 8) * 1) + 0px);
   float: left;
   margin-right: 5px;
   margin-top: 0;

}

... where 100% = 916px (it's a modal with a set max-width) and the last child has the right margin set to zero.

Other broswers (including IE9) correctly calculates this to be 110.125px; Firefox calculates this to be 111px (web inspector) or 110.133px (Firebug) - if you take the values and add them up again, I get 916.064px, which is wider than the parent.

My Firefox Zoom is set to 100%, however when viewing websites the actual zoom appears to be 150%. This came up when testing a new website that was not displaying correctly. We tested with another browser and all websites displayed correctly at 100% (used same computer for all tests).

Zoom was used a few weeks ago up to 150%, is it possible that although it says it is now 100% that it is in fact not updating correctly. If I change Zoom level now it appears to function OK except that the 100% display is very different compared to other browsers, it appears as 150% compared to the other browsers.

Thank you.

Hi,

I have sensory processing issues, and when I scroll on pages with background images, sometimes the text moves, and the background image doesn't, and this triggers my migraines.

I have tried using the preferences > content > colors options, and the "readable text on white background" style,* and they help, but on some sites (not this site) they make it impossible to see what I'm mistyping.

Does anyone know of a good way to block background images without this problem, or which can be toggled?

Hello, I'm wanting to create a FireFox theme via Stylish. It's been over two years since I've done this and have basically forgot all rules / tags / names FireFox uses in CSS for Stylish. How can I inspect elements of the FireFox UI elements to get their names so I can make a theme? I was hoping by now there'd be some type of wiki of somesort to have all the CSS names of the FireFox UI elements or some examples making a FireFox theme with Stylish. Thanks.

I encountered a problem with my search engine reverting to yahoo every time I re-launch FF. This is very frustrating. Somewhere I found that this can be related to add-ons. Although I didn't find any add-on called Yahoo in my list of add-ons, I found one called Search Engine for Firefox (or very close to this). I removed it and everything went back to normal.

The question is, what is that add-on? Where did it came from? I think it should be removed from available add-ons altogether, or, at least renamed to Yahoo search engine? I didn't install it specifically and was forced either by FF or some other add-on.

I've seen other users having same problem on the forum, why isn't that addressed?

Over the last week or so my Firefox seems to be dying about once per day. It just slows to a crawl, and then stops responding entirely and I have to use task manager to kill it. When I look in task manager it's taking up as much as 30% of my system resources, despite only having 4 tabs open at any given time. I've tried both refreshing and uninstalling Firefox, and neither has solved the problem. When I looked at the health report, I noticed something that's confusing me, namely the amount of add-ons and extensions it claims I have running. It claims that there are 7 extensions running, but there are only 3 listed on my add-ons manager, all of which I installed manually, which is making me wonder if there are 4 somehow hidden extensions that are causing me problems, and don't go away when I remove or refresh Firefox. Is there any way that I could figure out what these might be or get someone from Mozilla to take a look and see if they can figure out what's going on?

Hello everyone,

I'm running Firefox 50.0.2 on Windows 8.1 64 bits. For a while now it seems that Firefox is displaying jaggy fonts, looks like it's not applying any antialiasing whatsoever.

Checked in Chrome and all fonts are displayed nicely and smooth.

What I've done so far, with no results: - Updated my graphics driver (nVidia Geforce GTX 850M) - Reinstalled Firefox - Adjusted ClearType text

I'm attaching 2 print screens, one with Firefox and one with Chrome. Any help would be appreciated. Thank you!
