以下節譯重點，非常口語不修辭了。
What happens to my existing bookmarks when I install Foxmarks? Will my bookmarks get overwritten?
安裝了這套件後我的書籤會不會被蓋掉？
Foxmarks works by creating a single master file which contains all your bookmarks. When you install Foxmarks on a first machine, the master file contains all the bookmarks on that computer. When you install Foxmarks on a second or subsequent machine, Foxmarks offers you several alternatives:
供同步用的主書籤只能有一個，所以裝第一台 Firefox 時主書籤就會等同第一台的書籤，那裝第二台時有下列選擇：
* Erase the bookmarks on the newly installed machine, replacing them with the bookmarks from the master file; 把第二台 Firefox 的書籤全部蓋掉，換成主書籤。
* Erase the bookmarks in the master file, and replace them with the bookmarks from the newly installed machine; 把主書籤刪光
，改換成第二台的書籤
* Merge the bookmarks in the master file with the bookmarks on the newly installed computer. 主書籤與第二台的書籤合併。
Most people will choose the last option, as it's the one that guarantees that you won't lose any bookmarks. But sometimes you'll install Foxmarks on a machine that doesn't have any bookmarks that you want to keep; in that case, one of the other two options becomes more useful.
通常大夥都選第三種，其他兩種看你需求。
If you choose to merge the master file with the bookmarks on the newly installed computer, Foxmarks will join the two sets together, attempting to match up bookmarks that it finds in both sets so as to eliminate duplicates. More precisely, it will use one set of bookmarks as the initial list of bookmarks and will add to that any new bookmarks or folders found in the second (or subsequent) set of bookmarks. (Thanks, Enzo.)
如果要合併書籤，則兩邊都有的書籤「不」會重覆出現。
What are the "Upload Now" and "Download Now" buttons for?
Upload Now 跟 Download Now 這兩個鈕是做啥用的？
In normal operation, once you have performed initial synchronization, everything should be smooth sailing. Occasionally, though, you may encounter difficulties that will require you to perform some maintenance operation. The "Upload" and "Download" buttons allow you to force your synchronization into a known state. If you press "Upload Now," whatever bookmarks are on this machine will become the new annointed set of bookmarks to be synchronized across all other machines.
通常這兩個鈕用不到，不過碰上問題時你可能要自己動手做點事，那 Download 跟 Upload 就是讓你手動強制同步的方法。按下 Upload Now 之後，原有的主書籤會被刪掉，新的主書籤就會變成目前電腦上的書籤。
If you press "Download Now," the set of bookmarks on this machine will be erased, and the set of bookmarks on the server will be installed in their stead.
反之按下 download now 之後，目前電腦上的書籤就先刪掉，然後將內容直接換成主書籤。
Note that neither of these are "Synchronization" operations -- changes that you might have made (on other machines in the case of "Upload Now" or on this machine in the case of "Download Now") will be lost. Tread lightly, and employ these options only when absolutely necessary. Normally, you shouldn't need to use these actions.
這兩種方法都會造成某一邊的書籤全部再見，所以非到必要別用。
另外，這位同學，請愛用字典
Google Toolbar 裝完就有隨點隨譯了(滑鼠移上字就告訴你解釋)，也不壞。
