In my work computer, Firefox always gives "sec_error_unknown_issuer" error and only on HTTPS sites.

I have browsed the forums and understood that this is most probably caused by a sofware that performs HTTPS scanning. (See [this](https://support.mozilla.org/en-US/questions/1030927) and [this](https://support.mozilla.org/en-US/questions/1026631#answer-650916) answer)

However, I really don't know which software is performing the HTTPS scanning exactly.

Is there a way that I can determine which software is doing the HTTPS scanning so that I will be able to add its certificate to Firefox and hence be able to use the Firefox properly?

Thank you very much in advance

Regards

The search bar in the "Awesome bar" has recently stopped offering search suggestions, either from my search history or from Google itself. When I control-click in the search bar, "search suggestions" has a check next to it, and it is also ticked in the Preferences.

I've re-set network.http.speculative-parallel-limit to 0 and then set it to 6 and 10, with no difference. Re-starting the browser makes no difference.

browser.search.suggest.enabled = true browser.urlbar.suggest.bookmark = true browser.urlbar.suggest.history = true browser.urlbar.suggest.history.onlyTyped = false browser.urlbar.suggest.openpage = true browser.urlbar.suggest.searches = false

I've been having problems with Javascript seeming to just quit working after the browser has been running for a while over the last several updates, which affects things like comment loading on some sites, Java-based menus not working, etc. but I don't know if that would be related to this problem. A re-start didn't solve things in this case, not today anyway.

Every web page has annoying ads and popups. I have Norton 360 with a clean report. I have updated, reinstalled adblock plus. I have updated Firefox. Nothing works.

By default, adblock plus allows "Mysiterules" as enabled and I can not disable it.

Every website has popups that will not allow me to view the page unless I interact. If I open several tabs to view multiple pages, there's mystery advertising playing on a page with no visible ad.

It's making Firefox useless.

Why does Firefox still tell me that Adobe plug-ins need updating, when I've just updated them beyond the versions Firefox says to update??

On Plug-In Status page, Firefox says that I have the potentially vulnerable Adobe Flash player v. 19.0.0.185, and should update. But I already took this advice, and Adobe confirms that my installed version is 19.0.0.226. I ran the update at least twice (and of course I've restarted Firefox several times, and refreshed the page for good measure). Why does Firefox think I still have v. 19.0.0.185?

Essentially the same story with Adobe Reader plug-in 15.9.20069.28170. Firefox says I have this outdated version and should update. I ran the update at least twice (but unlike with Flash Player I don't know how to confirm that the update's been installed). The version Firefox says I have, and the advice to update, didn't change.

I updated two other plug-ins yesterday. Immediately after updating, when I refreshed the Plug-In Status page, those plug-ins disappeared from the "vulnerable" or "outdated" lists. It's only the Adobe Flash Player and Reader plug-in updates (which I also did yesterday) that Firefox seems blind to. I waited a day to see if Firefox would recognize the updates today, but it still doesn't. On this question-submission page, Firefox's "educated guesses" about my current browser list the older Adobe Flash Player and Reader versions that I've already updated from.

Some Images opened in new window or tab are upside down or rotated 90 degrees, but display in correct position when using MSIE.

I don't know yet if this is a browser or a server-browser interaction problem. The problem manifests one some user forums where members post jpg images that appear as thumbnails. I can right-click and select "open in new window" or Open in new tab". Either way some images open correct, some open rotated 90 degrees out of position sometimes upside down. If I use MSIE the same images will open right side up.

Every time I open Firefox a second tab is opened by ZenMate asking that I activate ZenMate. Since I have never activated it, it does not appear on the list of installed programs in Control Panel. I do not want to install it and do not want to be bothered continually with this tab, which is the active tab upon opening Firefox. If I remove whatever it is causing the tab to open, is there anything else that should be removed to completely remove traces of ZenMate?

When I try to do a newtab, this thing: "resource://jid1-g80ec8llebk5fq-at-jetpack/newtab/data/newtab.html" is in control and does not display my frequently used tabs. In fact, over the days, it has replaced all my tabs with tabs for sites I never visit, like Walmart, CNN, JAVA, flickr, tumblr. It also changes the edit button setting to 'class="unselectable"'. This is a huge retrogade step. How can I get rid of this malware??

This started happening after I began using the fullscreen mode and split screen view on the new OS X El Capitan.

I don't know what I did, but the history/downloads/bookmarks window (the one that pops up when you click "Show All History", etc.) is now permanently stuck in fullscreen. It takes up the entire screen, and it disables the menu bar and the Dock as a normal fullscreen would -- but it is clear this is a bug, since I can somehow move it around (see screenshot). No title bar pops up when I move my cursor to the top of the screen, and the usual Control-Command-F shortcut for toggling fullscreen doesn't seem to work.

How can I fix this?

This is a link that takes me to Pocket web site that appears the top of my bookmarks under "Show all bookmarks". When I click on it there is no option to remove this bookmark. I did not install Pocket. I looked at it and I am not interested. I do not want to give up valuable real estate at the top of bookmarks.

I have read many posts and the help page of how to remove it from the toolbar is not relevant (it is not there). I also tried disabling pocket in about:config by toggling to values to false. Nothing helped. It uses up a lot of space and very prominent, I find it very annoying and would like to remove it.
