I-Firefox Isithangami Sokwesekwa

When some pages are loading, getting 'Plug in container for Firefox has stopped working' error and closing out of this does allow the page to eventually load. Also has stopped auto-populating user names for sites that it's stored for me in the past.

I tried to access the http site of Google search by using the URL "http://google.com", through my Firefox browser in my desktop. To my surprise I couldn't access it as it kept on redirecting to the https site. I then tried to access it through my mobile using the same URL and there was no problem with that. I have attached screenshots of my mobile browser showing both sites.

What prevents me from accessing the http site of Google from my Desktop browser ?

On my web pages that display pictures, "next", "previous" and "index" can be selected by buttons. They work as before, but the button images no longer indicate that they are depressed. This worked perfectly well on the version of Firefox distributed by Debian as Iceweasel, but after the recent upgrade to Firefox-esr it does not. It also does not work on Firefox running on Windows 10, which is of course repeatedly updated. I suspect some feature of the configuration has been changed.The javascript lines that have no effect now are (to give one example)

    onmousedown=\"document['nextbu'].src='/U/nextdn.gif';\"

It seems that firefox is ignoring the onmousedown event, but correctly getting the click event. To check an example web page, look at http://molard.ca/C/H/240/4003.html

This Win 7 PC has been off-line for 4 months. When switched on FF updated from V38.5 to V45.2 (64Bit) Everything worked except the Native PDF plugin. I've gone through all the on-line fault finding, (enable/disbale the plugin, remove mime types file and restart, ensure that the application is set as display in FF, etc) but it refuses to work. I've disabled all the add-ons apart from the pdf plug-in but still nothing, the link doesn't even come up in the url window.

To get around this I've downloaded Adobe Acrobat Reader DC and pdfViewerSwitcher ( 0.8.2 : jid1-UXDr6c69BeyPVw@jetpack) and these seems to work OK. However this is far from ideal as I'd prefer not to have Acrobat on this PC.

Any ideas or are there any other PDf Plug-ins which work ?

Thanks.

ESR 45.2.0 locking up since update from ESR 38. Various video programs. Similar to problems that I had 9/2015 before switching from regular FF to ESR 38. Very frustrating since I was not having this problem before the recent update of esr from 38 to 45.2.0. Any way to go back to ESR 38?

If the first word of my search query is "minecraft", then the search always goes to the minecraft wiki at minecraft.gamepedia.com.

But I don't want that. I want Google to search the web for information about minecraft. I am almost never asking for information from the wiki, and if I am, it will show up in a normal google search.

Google is my default search engine. Minecraft wiki is not even on the list. This happens whenever the first word of the search is "minecraft".
