ArchWiki main page now has root language categories links

Question

I have added root language categories to the main page. All languages that have, to my knowledge, and at least to some degree, completed work on their category tree have been included.
If you think a language root category has been left out, please accept my apologies, and PM me the link to the root category.
BTW, if you don't know what root language category means, take a look at this page:
http://wiki.archlinux.org/index.php/Category:English
That page is the English root category. I have been able to track down three additional root categories, for Russian, Thai, and Polish.
Some of them need some polish (no pun intended), but I'm sure we're on the right track. Also, it seems that maintainers of existing translations are not catching up to the new categorization, so I would like to ask all capable translators to try and implement the new category tree.
The early version of the category tree (now unmaintained, because I haven't time) can be found at:
http://wiki.archlinux.org/index.php/Arc … egory_Tree
The English tree has already been populated with many articles, so you may want to try there for a more complete tree (unfortunately no tree view there).

Answer 1

(1) Firefox's built-in post-crash page has not been a real HTML page for a long time (for example, from the time of Firefox 22, see: [https://support.mozilla.org/en-US/questions/968212 Want to save LOTS of versions of "Restore Session.xht" from the "oops ..." page for later use]). If you had this working differently with Firefox 25, that might have been created by an extension.
You can check to see whether extensions are disabled or need an update on the Add-ons page. Either:
* Ctrl+Shift+a
* orange Firefox button (or Tools menu) > Add-ons
In the left column, click Extensions. The disabled extensions cluster toward the bottom of the list. To poll for updates, use the "gear" button above the list and choose Check for Updates.
If you used the Reset feature (or Firefox automatically did a reset due to some problem during upgrading), you will need to reinstall missing extensions. The reset feature creates a folder on the desktop named Old Firefox Data. Do you have that folder? There may be data you can recover from it.
(2) There are many ways for history to get cleared, both internal to Firefox and external. Could you double-check your Privacy settings?
orange Firefox button (or Tools menu) > Options > Privacy
* The "Firefox will" drop-down says Remember History: Firefox shouldn't be clearing history, but an add-on or external software could do it
* The "Firefox will" drop-down says Use custom settings for history: inspect the "Clear history when Firefox closes" setting to make Firefox isn't set to clear history. Also check your add-ons and consider external software.
Firefox normally accumulates months of history. However, some of Firefox's database sizes are based on disk space available. If your hard drive is very full, Firefox might reduce the amount of history stored.
