How to restore tabs of Developer Tools' Inspector pane after they mysteriously disappear?

I initially thought this was a UX issue, but it appears it may be a straight up bug; I wanted to ask here first before I report and assess if others are observing it. Regardless, its a pretty horrible problem either way making web development with Firefox an incredibly frustrating experience, to say the least.

Essentially, the problem is this: sometimes, seemingly at random, when I click a tab in the Developer Tools "Inspector" pane (Rules, Layout, etc) the entire inspector pane (aside from the DOM) will just vanish. I have repro'd it with the dark theme and with the pane docked to the right, but its been difficult to get it to repro in other conditions (clean profile, light theme, etc) since there is no obvious consistency in whether it occurs or not; sometimes it won't happen at all for a while, and sometimes it happens every other time I click a tab.

When it does happen, I've tried everything I can think of but I can find no way to restore the tabs, even by reloading the page, closing the developer tools, switching between panes, switching between DOM elements, trying every option I can think of, etc. except by closing the entire browser tab and opening another. Its infuriating. to say the least, and significant hit to my productivity in Firefox. Any ideas?

The "upload images" feature of this page appears broken, as it gets endlessly stuck on "Uploading..." (not to mention primitive—you can't just copy and paste them directly into post like any modern site), and there isn't any obvious support for Markdown (maybe there is, but it isn't exposed anywhere), so I'll just do things the archaic way and post links to screenshots of the problem on imgur:

I developed a web site with a protected download area (using .htpasswd) containing many pdf documents and download exe files.

The website works correctly with all Microsoft browsers as well as Chrome and Opera.

It also works correctly with Firefox the first time you open or download a file in a session. On subsequent attempts to read or download a file, I get and error of the form "C:\Users\tom\AppData\Local\Temp\0tdBH5YZ.pdf.part could not be saved, because the source file could not be read."

If you shutdown firefox completely and re-login to the website, it again works one time.

I use a very simple php script to support the download where the relevant function is:

function Download($file) { $rtn = FALSE; if (file_exists($file)) { $rtn = TRUE; $size = filesize($file); $type = filetype($file); header('Content-Description: File Transfer'); header('Content-Type: application/octet-stream'); header('Content-Type: '.$type); header('Content-Length: '.$size); header('Content_Transfer-Encoding: Binary'); header('Content-Disposition: attachment; filename='.basename($file)); header('Expires: 0'); header('Cache-Control: no-cache, must-revalidate'); header('Pragma: public'); ob_clean(); flush();

$lr = readfile($file); if ($lr == FALSE or $lr != $size) { echo "error in readfile
"; $rtn = FALSE; } } return $rtn; }

Hi there, While working on a sound effects site, I somehow downloaded malware to my Mac. Now, every time I do a google search (in the address bar, and also in the google search bar, which I've since just removed), the google search results no longer come up. Instead, I'm redirected to a search engine called: http://search.primeinfospot.com/?tp1=dbc19016-3c27-4231-bf81-d50a9c367fda&kw=sarch

Going through my search history when this happened, it seems it came out of this "Browser Update" (here's the start of the site, removing all the gobbly gook that followed it but maybe but don't click on it to be safe?)

https://www.logicalplatforms.com/

I've tried simply adjusting my firefox settings. restoring default but firefox seems to think this is my default. any ideas on how to remove this and insure it's not doing other bad things to my comptuer? thanks!

I tried to migrate my profile and data for my firefox on an iMAC to my new windows laptop. NONE of my passwords and user names have worked after the last few upgrades forced by Mozilla on my desktop. So i was able to update my support password on Mozilla, but when I was going to reset my password on my desktop to try to set up a sync to my laptop I got a message that I would lose all of my settings, bookmarks and preferences. That is a very bad way to do password upgrades. So, today, I really need to move all of my profiles, bookmarks etc to my laptop, but can't get sync to work at all, without the threat of loosing over 10 years of work. Some of your features are very draconian and difficult to manage. Add to that, the only support is by reading through years of comments, most of which do not work. So what is a user to do??????

Hey guys,

I'm using FF 63.0.1.

As of this update, FF no longer shows my visited links in a different color.

I haven't changed anything. My browsing history is still being saved (I have "Remember History" selected). I never use Private Browsing, or clear my history on exit. And in Options > Colors, "Visited Links" is still set to a unique color. Any idea why this is happening? Thanks!

This is probably something to do with how mail.com handles this but it works fine in Edge.

1) I installed YouTube Video and Audio Downloader extension; as suggested, I added native-client 0.7.0, & ffmpeg as well. The options page for the plug-in showed native-client as registering, but not ffmpeg. I pasted /usr/local/bin/ffmpeg in the location line for ffmpeg, but to no apparent effect. Is this the correct thing (I barely speak Terminal), & how can I tell if it worked? 2) For the Free Download Manager Extension, I attempted to install the latest Free Download Manager 5.1.37, but my system wouldn't allow it. (A lengthy log report appeared instead.) Maybe my computer is too old (iMac7,1), though it runs Yosemite (OS X 10.10.5) & the program should be good for anything later than OS X 9. Any suggestions e.g. should I try an older version of FDM?
