Working perfectly for me with the latest Firefox version Bewertet mit 5 von 5 Sternen

By default all Google translation opens up in a new tab. That is the way I like it. That can be changed in the addon's options. Right-click any page to translate it via the link in the context menu. Or select text first and click the relevant link in the context menu. The translation icon at the top of the Firefox window is also working fine for translating full pages. That icon can be moved around via Firefox customization (right-click the top of Firefox, and click "customize" in the context menu). In the past that icon sometimes did not show up right away after installation, and only showed up after restarting Firefox. So if problems, try restarting Firefox to see if it helps.

Version 3.5.0 is working fine for me Bewertet mit 5 von 5 Sternen

It looks like the problems have been fixed. Translation link shows up in the context menu when text has been selected for translation. And full page translation is working for me too.

Translation links in context menu disappeared in beta version Bewertet mit 4 von 5 Sternen

Beta version was working. But not now. Also, at the very top it says: "Translate the whole entire page or just a selection using Google Translate." If you can't add a link there to the beta version I suggest adding this there: "See the 'About this Add-on' section below for a link to the beta version that fixes compatibility with Firefox 40 and above." The beta version was working fine for me. Most people are not going to try it though because it is not mentioned at the very top. So they try the old version at the top ('Add to Firefox'), see that it does not work, and see the many bad reviews below. Then many or most give up. While this is getting fixed I am using the "Translate Now" addon.

Great because there is option to open in new tab Bewertet mit 5 von 5 Sternen

Unlike some other Google translation addons this one has a setting to "Open translations in new tab". I do not like covering up the page I am trying to translate.

The "About this Add-on" info needs to be updated to indicate that "no restart" is only for initiating translation via the context menu. To get the translation button to work one has to restart Firefox. Then the translation button works.

Working great overall, but a problem remains. Bewertet mit 5 von 5 Sternen

It is working great in Firefox 15.0.1 for the most part. One problem that happens from time to time is that when translating a selection the text is copied over in ASCII or whatever it is called. Where blank spaces are replaced with %20, and accented characters with other % stuff. Here is an example of a line of Portuguese: Eu%20tinha%20esquecido%20desses%20problemas%20de%20conflito%20de%20edi%C3%A7%C3%A3o. It does not happen all the time with Portuguese or any language. Even with different text selected from the same page. When this happens Google does not translate the text. There is nothing in the right-side pane.
