Tuning

 

browser.sessionhistory.max_entries

browser.cache.memory.enable

browser.cache.disk.enable

# True

browser.cache.memory.max_entry_size

# set a number in KB

browser.cache.disk.capacity

#

browser.cache.compression_level

This setting determines whether Firefox compresses the data in the disk cache

browser.cache.check_doc_frequency

This setting determines how often Firefox checks the page you're viewing against the cached version it holds.

3: Firefox automatically checks and only reloads the page if it seems outdated
2: will never check and always load the cached version
1: will always check for a newer version of the page and reload

browser.cache.disk.parent_directory

D:\tmp\firefox\

 

# Disable Firefox Animations

about:config

# Enable Firefox Pipelining

search pipelining

# 查看 plugin memory usage

# 安裝 plugin: "addons-memory 2016"

RAMBack will cause Firefox to issue an internal notification to free up memory that is otherwise held for performance purposes.

Firefox 瀏覽有點慢

 

在 Apache2 Web Server 上開啟了 cband 後,

總覺得 Firefox 反應有點遲緩.

之後用 IE 上再試, 一切正常 ....

之後在 Firefox 鍵入

about:config

一看, 原來 Firefox 是相當進取的 ...

network.http.max.connections-per-server            # default 15
network.http.max-persistent-connections-per-server # default 6
network.http.keep-alive.timeout                    # default 115

看來我 cband 的設定值太少了.(CBandRemoteSpeed 120kb/s 30 3)

之後改成 CBandRemoteSpeed 120kb/s 30 5, 一切回復正常 ~

Session - sessionstore

 

1) 查看 Profile 的位置

 URL: about:support
 Find: Profile Folder

2) Backup Session
 Make a copy of the sessionstore-backups folder.

3) Restore Session
 Close Firefox
 Copy a file from the sessionstore-backups folder to the main profile and rename it
 i.e.
 sessionstore-backups\recovery.jsonlz4 -> sessionstore.jsonlz4

嘗試 restore 的次序

1. recovery.jsonlz4 (latest version of sessionstore.jsonlz4 written during runtime)
2. recovery.baklz4 (previous version of sessionstore.jsonlz4 written during runtime)
3. previous.jsonlz4 (cleanBackup: copy of sessionstore.jsonlz4 from previous session that was loaded successfully)
4. upgrade.jsonlz4-<build_id> (backup created during an upgrade of Firefox)

Notes

sessionstore.jsonlz4 <- 正常關 Firefox 時才會出現.

If Firefox doesn't use the sessionstore.jsonlz4 you copied then check

"History -> Restore Previous Session" and possibly "History -> Recently Closed Tabs/Windows"
